I took a look at the Ghidra ones (because I use Ghidra), and I'm unimpressed: https://github.com/bikini/exploitarium/blob/main/ghidra-12.1...
The first requires being able to overwrite binaries in the Swift tool directory. Yes, if you overwrite binaries executed by ghidra, you can trigger code execution. This is not a surprise.
The second, idk, I'm not familiar with TraceRMI (but it's probably worth noting that "RMI" stands for Remote Method Invocation).
The third is not a vulnerability in the slightest, they just demonstrate that native 7zip parsing code is reachable. Maybe there is a bug in the 7zip parser, but without that it's meaningless.
Was just thinking it would be hilarious if these were all known CVEs hiding the next Shai-Hulud inside of them and waiting to compromise security hobbyists rushing to download them.
It wouldn't be the first time!
The Gitea one looks marginally interesting, but is probably not exploitable in practice (unless Gitea or whoever else isn’t properly isolating jobs on dedicated VMs). I suspect GitHub Actions has similar behavior and is not considered exploitable because the user is assumed to already have local, non-namespaced root access.
Gitea action runner has a bunch of different ways to setup and doing the isolation properly looks tricky. The documentation doesn't provide any isolation tests to administrators, either.
The biggest mitigation is that gitea documentation discourages you from using action runners from untrusted users. Not flawless security, but it's something...
I'm no expert on any of these programs, but that's kinda the problem, isn't it? No single person is an expert on every codebase supposedly exploited in this repo.
After a bit of research, the Firefox one seems plausible to me. But, I haven't actually tried the POC. The explanation about the private-data and untrusted-input flags is plausible but I'm not an expert on Firefox's internals, maybe that's not actually how it works.
This just sucks, all around. Are we going to need every open source project gawking at the same repo full of stuff that has nothing to do with them, on the off chance that someone discloses a vuln that does have to do with them? Is this some kind of performative complaint about high friction in responsible disclosure? Well great job dickhead, you've just made a system that's even worse. Nobody benefits from this. Yuck yuck yuck.
I actually prefer them being public than in some governments or corporations toolbox
> Nobody benefits from this
Disclosures always enable more secure software to theoretically exist,
even if nobody follows through creating it.
They often do.

This reminds me of someone submitting a (clearly vibecoded) vulnerability report claiming to have found a way to execute arbitrary SQL. The project in question? An SQL server... https://github.com/tursodatabase/turso/pull/4322
I immediately saw the Ghidra one and was thinking: huh?
The bigger takeaway is someone that smart is pissed off and dropping their shit with zero warning... but hey, that's just like, my opinion man.
You don't need to be pissed off to decide that immediate public disclosure is the best option.
Ok, I don't know their emotional state. Fair point.
Maybe I'm projecting my own biases ;-)
Meanwhile, some dude was just playing with claude and accidentally made his repo public.
Went over a few of these with a pretty keen eye, and they aren't that particularly interesting. The Docker one is just a weird bug, it's not a vulnerability, and certainly not a "0-day" (which is a pretty loaded term and people expect bad stuff to happen).
The nghttp2 nghttpx one is more interesting, and could potentially be used for phishing, but it's very hard to line up properly because the request queue is non-deterministic so basically impossible to target a specific victim (assuming proxy traffic).
The VLC one is just a straight-up crash/bug. And VLC crashes all the time when using weird codecs, so that's nothing new.
Am I missing something here?
0-days-vibes-vulns? There should be a new category, for spotting and handling the em-dashes of this brave new world of vulns and making the old fossils like me only picking my head up for the old painfully still hand-crafted artisanal ones instead. A kind of label, like free-range for eggs, in sum.
Yes, big pet peeve of the new world. Every em dash is apparently an AI trigger. Back in my day, they were a sign of great respect within my people.
I used to be an em-dash user, but now my opinion is that I’d rather be perceived as someone who does not want to be confused with an LLM. So I’ve changed my writing style.
My feeling is that my writing doesn't sound anything like an LLM, and so if someone thinks I'm an LLM because I used an em-dash, that's on them. That, or I royally screwed up and need to do a better job as a writer. At least with today's LLMs.
They're just so handy! I do think LLMs tend to use them in a specific way, though.
So maybe tweaking your usage (ex. no spaces around them) or using a technically incorrect en-dash might offer the desired effect while subtly signaling that your message isn't AI-generated.
I still use them — mostly for pauses — but I'd like to think my voice sounds distinct enough from an AI that people can tell.
I for one am striving for clarity and couldn't care less about being confused with AI.
However I've only ever used regular dashes. How do you type an em-dash? Is it OS specific? I've taken to using Emacs insert-char with a list of frequently used ones in my scratch buffer. My memory for Unicode is unreliable.
Code switching in the post LLM era.
I propose that humans use Unicode U+2E3B three em dash ⸻ it is an impressively long character.
let’s market it as “human dash”
And if it ever catches on with LLMs ⸻⸻ we just make it longer
I still use them frequently. On iOS you just tap the hyphen twice, and it inserts an em dash—sorta like that.
I might like to see a collection of pre-2022 em-dash usage—a subset I suppose of the Low Background Steel category (https://lowbackgroundsteel.ai).
The question is whether the m-dashes are surrounded by spaces or not. The spaces are utterly maddening. But yeah, RIP the mdash, who would have thought.
It’s so they don’t train on AI data, right?
You completely misunderstanding the comment feels like an AI trigger
Are they all actually 0-day? I think a lot of them are from disclosed CVEs/code that were already fixed upstream. It often seems like the term "0-day" has lost most of its meaning today and people often use it to refer to any exploits.
Repo claims
> A single archive of public exploit PoCs and vulnerability research writeups. At the time I post these, none have been reported. Feel free to report them yourself and take credit for the CVE if handed out lulz. Please do not abuse these. I do this so to allure people into the field, and I've always found this is the most efficient way.
Which is roughly the definition of zero day. Whether the contents of the repo reflect the above claim is something else entirely.
> Please do not abuse these.
Reminds me of Jamie Wolf's joke about bestiality laws. Who are those for? What stops most people from bestiality is… not wanting to have sex with animals! For people who do want to, what, they won't because of… the law??
Who will this comment stop??
Well, it's a joke because the problem becomes apparent after you think a bit about it. The exact same reasonig can be applied to anything illegal, criminals are criminals because they don't respect the law, so you could try to say that laws are useless. Reality is, if something is illegal not only someone can be punished after the fact, but in some cases also preventive measures can be taken.
Regarding the comment, it isn't going to stop anyone. Most people will not do cybercrime because they're honest. Of the remaining, the risk of being sentenced to jail time will instead stop some people, even if not all of them.
Those seem like two different scenarios though, right?
The point of beastiality laws are to give society some recourse to punish people who abuse animals.
There was a very famous case back in Washington state back in the early 2000s where a group of men were sexually abusing horses. It was uncovered because one of them died, and the other could only be charged with trespassing because it wasn't illegal at the time to sexually abuse animals.
The laws are to punish the act once discovered. Not to inhibit it, primarily. Which I suppose cuts down on the incidence of the act in the long run,
That’s one school of thought. Law as a tool to punish those who have committed a prohibited act, mostly reactive.
Others consider law a way of encoding the group’s existing rules and norms.
In that view, making something illegal or mandatory is not a prerequisite for punishment: it’s the actual main point.
The threat of punishment is meant for those not deterred from an act by the simple fact it is illegal (and the threat only works if enforced).
Others put it the other way around, and see law as social engineering, a way to shape the group, either through the encoding itself of the desired behaviours in law, or through deterrence. Or both. If what one is after is either power or legitimacy, they need compliance more than punishment (can’t rule once you’ve chopped everyone’s heads off, or once the mob has put yours on a spike).
It’s also sometimes used as coordination (which side of the road we drive on).
And there’s also law as dispute resolution (if your neighbour’s hen lays an egg in your garden, who does it belong to? Yes, it’s ridiculous. Yes, some places have one or more laws for that). Which, incidentally, both requires and provides legitimacy. Funny, that.
And probably many other kinds / points of view, with many different purposes, intents, and mechanisms.
Anyway, all that to say law is vast, fascinating, and utterly tedious. And apologies for the tangent.
If it stops even just 1 person once, isn't it already worth it?
> Who are those for?
The people who want to see the people doing bestiality punished
I don't want to "see" any of it...
The jury, maybe.
Either the fear of the consequences of breaking the law, or that the most effective way to reduce crime is to remove criminals from the population so over time these people being in jail or worse decreases the crime rate. They don't have to care about breaking laws in the abstract for the law, properly enforced, to reduce crime.
RCE has no meaning either in these situations. The "remote" part is usually an ssh root session if it means anything at all.
There is going to be a flurry of this sort of stuff as the AIs get smart enough to find them. It will naturally die down as the legitimate ones are fixed. Yes, there will always be some level of this, but I’d expect it to be low and the exploits found to be increasingly complex. This is a time of transition.
> a flurry of this sort of stuff as the AIs get smart enough to find them.
I really think this characterization is misleading. It's not "getting smart", only more tailored toward a specific usage, better curated dataset, better harness, better prompts, better labeling of results, documentation of failures and success, etc.
The outcome is (hopefully) overall better but this anthropomorphized wording makes it sound like AI itself is somehow changing or evolving. No, both academia doing fundamental research, industry making it available commercially, and finally security researchers making the entire tooling and process packaged as a service are actively shaping it to make it better. There is no "it".
Do you have a definition of "smart" such that there is something an AI could do to prove itself intelligent?
Or are you just defining "fast" as something only horses can do, and considering that a useful insight about cars?
A future AI may be intelligent, but LLMs are clearly not. They have no agency, no ability to reason, and no world model. The most effective way to use them is to treat them as next token prediction machines, because that’s what they are.
Yes, of course. I’m definitely anthropomorphizing as a shorthand. I’m the first one to say that these models are just a lot of matrix math.
> It will naturally die down as the legitimate ones are fixed.
Seems like we're already in the middle of this phase, but rather than dying down, the 'reports' have just gotten more noisy and obtuse, making it more difficult to establish the actual degree of threat / attack vector.
And if you are a state agency who'd like to keep the undisclosed zero-days you rely on secret, spamming maintainers with reports makes sense.
As a bonus if you find any actual zero-days in your mass-generated ones you don't report it and get a new one to play with.
I mean. Makes sense until adversary states start walking through the same doors you’re using. At which point you might regret that maintainers are too flooded to deal with it.
Assuming, of course, said state agency is operating under sufficiently strategic governance and management…
Honestly execution complexity is over time becoming a lower and lower barrier too.
I want to rush to git clone, but as things are, the odds are extremely high that this kind of things that are too good to be real are honeypots and something there will compromise your machine or make your llm start working for someone else...
Then, don't rush and take a few minutes to set up a virtual machine.
What about all the virtual machine zero days?
Pretty unimpressive as security vulnerabilities. It would be better to just say these are simple bugs for the most part.
all vulnerabilities are just bugs.
Vulns are a subset of bugs. What the above commenter is saying, is that some bugs don't belong to this category.
But not the other way around, which makes them different.
I also have a library of bugs I found using Claude Opus 4.8 through the Customer Verification Program. Undisclosed, Atp I dont even know if they have been found by someone else. But just like this repo
Theres a bunch of very specific scenario DoS bugs, buffer over/ underflows, that will get caught by ASLR and whatnot
When I report serious ones, mostly the devs will respond with something like, yeah, thats how we designed it in a dangerous way, so that the layer above or below can solve the issues, and other footgun stuff.
Most of the exploits are for opensource/free software.
I don't know what methods where used to find these exploits but I am starting to think security through obscurity might not be a bad thing in this day and age, where someone can just let bots loose on your codebase.
llms are fantastic disassembly partners, they're quite good at labeling functions from various dissassemblers -- the net losses from losing the benefits of open source , imo , outweigh the protection afforded by hiding your source code in yet another layer that is more and more easily unrolled through automated procedures.
And isn't it also mostly a transitioning issue. Those open codebases will be constantly scanned for potential security issues and getting more and more hardened. There are probably a lot of easy wins that are going to be discovered over the next few years but it should taper out after a while.
Fair point but it assumes we all have access to LLMs with the same capabilities.
I don't think that's exactly it. OSS only needs someone to have a strong LLM to check for bugs. If your software is proprietary, it's a competition between just you and whatever model you have vs any attacker and whatever model they can lay hand to.
I don't see the difference.
> OSS only needs someone to have a strong LLM to check for bugs.
The same applies to propietary, closed-source code. It being closed-source means that the source isn't generally available, but the executable is. Hence, someone with a strong model can still reverse it and find vulns.
disassembly only applies to client side software
something like nginx could arguably be more secure if it was closed source
(I am a proponent of and contributor to open source)
Only until a single server running nginx is hacked and the binary leaked though...
Um, the nginx binary would have to be in the hands of hundreds of thousands of server operators. And the set of server operators is rich in the kind of person who would attack it. Not to mention the huge number of leaks you'd get.
Maybe if it's some server-side software that you only use yourself...
Open source is a good thing, but I don't think what you are proposing is accurate.
A different way to frame this would be that those bugs would never be surfaced or exploited if the software were proprietary.
Presumably, one could let the bots loose on your own codebase first. The question is one of financing of course. If your end users are enterprises willing to pay for a support contract, they probably care enough about not getting hacked to endure the higher prices that would let you throw enough tokens at the problem. Other open-source projects might have a harder time.
> I don't know what methods where used to find these exploits but I am starting to think security through obscurity might not be a bad thing in this day and age, where someone can just let bots loose on your codebase.
I'd love to hear why you think obscurity is bad, if you now think maybe it's good in the LLM age?
I'd also be interested if you could describe exactly what or how you think security through obscurity works, or doesn't?
I've been thinking a lot about how to better teach this concept, so I'm looking to understand exactly how everyone thinks/understands how it currently works, or should work, or what it should do. I don't care about the "correct" answer, (I have ddg too :P) I'm interested in general expectations from SWE's that I might teach at work, instead of opinions of security eng speaking about theory.
Security through obscurity can make something a bit more secure in practice by annoying an attacker IF AND ONLY IF you're not relying on the hidden information remaining secret in order to the system remaining secure. E.g., if you're using a broken cipher and assume this is ok because no one knows which cipher you're using, you're gonna have a bad time.
In the case of FOSS software, it is generally recognized that the small advantage of keeping the source secret is far outweighted by the contributions and vuln reports you get if you publish the source.
"one ought to design systems under the assumption that the enemy will immediately gain full familiarity with them" - Claude Shannon
If you believe this, then why did you say?
> starting to think security through obscurity might not be a bad thing
Because of asymmetric differences, I don't have access to powerful LLMs but attackers might. And also the complexities of software dependencies (supply chain vulnerabilities), my software depends on packages not in my control and I don't have time to audit the entire stack.
trying something new? this is interesting. the problem is that submitting reports is too slow. if you find one then your not supposed to share. but then over the next 90 days you learn no one cares and 13 other people submitted it before you, 43 after. maybe better that we just know. so we can run code we can trust sooner. zero is the proper number of dependencies. otherwise assume its broken.
I'm going through each one, and it's fascinating to see things like this. The UAF principle in c-ares is really interesting.
The problem ultimately came from not being able to prevent stale pointers. The attack works by figuring out the size of the stale pointer, then spraying memory with data of the same size, and finally achieving RCE (Remote Code Execution). How do people even come up with ideas like this?
But do people actually find these vulnerabilities on their own, or are they using LLMs? I was curious about how these vulnerabilities work, so I tried asking my dear friend Mr. CLAUDE, but he immediately threw an error and ended the session because it was a cybersecurity question. Enterprise APIs block even the analysis itself, so it's amazing that people can actually pull this off in practice.
People have always used tools. Some people have better tools than others. I guess the line is thin whether they found on their own or not.
If you want to chat with Claude about this, I'd recommend using Opus 4.6. IME it's happy to talk about (and even write) PoC exploits
I imagine this is a large open model like GLM5.2 etc
le sigh, c-ares. Very predictable outcome. If you ever find yourself entertaining the idea that you will simply write non-blocking network protocol stacks in C with manual lifetime management, slap yourself. It doesn't matter if you think you are a super genius of unimpeachable taste. The job is impossible.
Thank goodness I use a GC language
A surprising amount of documentation if the actor was just LLM-dropping these..
Why is that surprising? LLMs can churn out arbitrary volumes of "documentation" in an instant.
That seems trivial for an llm to provide.
Mythos has been achieved internally
we have got to stop putting our bank accounts and SSNs on computers
We need our infrastructure to stop treating bank account numbers and social security numbers as secrets. At least in the US, bank account numbers appear on physical checks and are required to be shared in order to do an ACH transfer, and a social security number is not supposed to be used as an identifier (unless to the Social Security Administration itself) or as a secret password.
Ideally, nothing nefarious should happen if both of them were listed and queryable publicly.
Hang on, can you actually do something nefarious with just the bank account number?
If someone has your bank account and bank’s routing number (which is also not secret), they can make fraudulent ACH transfers and payments from your account. Of course it will most likely be caught as fraud some time after the fact, but just those two bits of not-secret info are enough to grief someone.
And both numbers, plus your name and address and a convenient sample of your signature, are on every check you’ve ever written.
AFAIK that's US thing. In normal countries bank account numbers are not a secret. The worst thing that can happen is someone sending you money.
It’s quite ridiculous that we haven’t been able to build a modern identification system capable of replacing SSNs in the last 30 years.
You can buy your SSN for $6-$10.
You all need a better system than US SSNs

A friendly reminder that a 0-day is a vulnerability that wasn't known until after a malicious actor exploited it. If someone publishes a PoC, it is not a 0-day, just a vulnerability.
No, the days start counting from the availability of a patch.
I was thinking that the other definition was right and this correction was wrong.
Then I did some searching and found multiple examples of both definitions in use, making things murky.
So I turned to Merriam-Webster’s dictionary: “ of, relating to, or being a vulnerability (as in a computer or computer system) that is discovered and exploited (as by cybercriminals) before it is known to or addressed by the maker or vendor”
And of course they use an “or” to make it ambiguous as to whether the days start counting when the vulnerability becomes known, or when the vendor has addressed it.
what if a path is never released?
I've only heard it used as Retr0id's definition.
I think people may miss the point of a repo like this. Individually these are small puzzle pieces that can't do anything. Put them all in one place and it becomes easier to pick up pieces and try them together to see if they fit and build something bigger. Get enough pieces to fit together and you actually have something. This is the 'FOUO' idea in security. Enough open information gathered together in one place crosses the boundary from 'just public info' to 'secret stuff here!'. Now we have automatic puzzle solvers (coding assistants) a repo like this becomes a lot more meaningful.
Yep and typically none of this is meaningful unless you have no security practices at all. You can't have it both ways. Every security team says these things are all critical even though, for example, it's only being used internally. Cool, so you somehow have our network cert, are on site physically, have compromised a laptop fully without all of our tools detecting weird shit, have a password, admin access to the repo, somehow are spoofing MFA, etc etc. Yeah it all adds up, but as an admin I'm just fucking done dropping everything for these kinds of things.
That's one way to do it.
> At the time I post these, none have been reported. Feel free to report them yourself and take credit for the CVE if handed out lulz. I do this so to allure people into the field, and I've always found this is the most efficient way.
I've been a skiddy, he would have believed this. Thankfully, I've grown a bit, and can see this for the transparent, "I'm angry and want to hurt others so I will feel a little less alone", it actually is.
I'm sorry you're so angry dude (me too), but as someone who's joined the blue side, we'd appreciate it if you gave us some kind of heads up, the bad guys generally have a lot more time to scroll for new payloads than I do. Not all of us deserve the kindness of a heads up, but every single one of our users deserve it. Don't punish them because you're mad at someone else.
You can flex on the idiots you're trying to flex on, without hurting people. Even an email to security@[that_project_domain] saying "hey, I've published these" would move you from the group of people I see making the world worse, into the group making it better. (You don't have to, obviously, but making the whole world worse wont make you less angry.)
User/admin discretion for software they use should be a big factor, sometimes getting burned is how you learn to play with fire. Or decide that having your data/participation disrespected means you need to set harder boundaries. My solution is to try things in isolation, run very few services, try to avoid becoming dependent on the online, appreciate the offline and local first.
While i can follow your path, maybe because i see the same, i sadly have seen in groups of friends how this can go sideways very fast. If you report things, some companies gone treat you as a criminal/offensive actor and even go legal actions against you even you just tellem here you got this vuln.
Sure you than can do it anonymous and so on but point is : its not like every actor that gets notified will react thankful to it. Some even just ignore it.
How bad are your security practices that these tiny obscure things matter? None of these findings that show up here on HN should even make you flinch. The alarmist takes on this stuff is fucking exhausting and I'm tired of security teams bugging me about it. Do your job and this shit doesn't matter AT ALL.
I said "doesn't matter" to someone once... the resulting lesson came in the form of a reply from the whitehat researcher (waves, hi brian!) a 16step exploit chain resulting in a one click full account takeover.
I'm equally annoyed and over the alarmist takes. But I don't think it's fair to group mine into it. I'm annoyed at seeing discard respect for others into the same void everyone is happy to toss quality.
Do these tiny things matter? No, not to the default-panic-level everyone adopts when they see 0day, or CVE... but duh, I'm now just repeating exactly what you already said. That no, for the record is mostly because I don't use any of these, not just because they're boring exploits. While I always look, I default assume anything CVE is boring/pointless. But I still read them.
But then, I'm not trying to convince the owner of the repo. I'm trying to discourage the theme among researchers that "no one cares", because I have seen researchers disclose bugs publicly, that we'd be eager to pay out on, because they disagreed with the decision on their last report.
I've fixed bugs being actively exploited against our users, that was found/fixed only after a whitehat report for something adjacent (we pay on those btw, and you should too). I don't wanna live in the world where it's easier for the bad guys, the only way we get there is once "everyone knows", you gotta report the all bugs that you can turn into an exploit. I don't want "the whitehat researcher culture" to move towards, who cares' dump the PoC on github, screw anyone that could be hurt by the bad guys, they deserve to be punished for the incompetence of others. SWE's are shit at security, security researchers are shit at SWE, the only way we get the good outcome, is if they're willing (and encouraged) to work together.
That’s a whole lot of “we” to not mention which company you’re at that supposedly plays well with security researchers/has a proper bug bounty.
