I am not following how someone snuck the files into the release.
All I read was that it creates a directory from the build file but seemingly no description how new files or added dependencies slipped by. Was `cook.pth` a dependency that got automatically downloaded from PyPI on install and then the build system put it into dependencies?

A stolen PyPI token used from the attacker’s own machines fits the evidence less well.
Makes sense. It was that a maintainer or the private pipeline was attacked and the malicious dependency was injected there by squatting on the maintainer's local copy rather than the dependency being hijacked for everyone. Very clever.

What's interesting here is that this will only affect those who did not migrate off LiteLLM after it was attacked the first time.
I'm not saying everyong should migrate after there's a vuln, but I'm definitely saying that. Unless it's something huge and foundational like a programming language (PHP gets a second chance), just migrate within the next couple of weeks.
I didn't even have it installed the first time, so the ideal programmers, (read, your competition), actually suffered 0 vulns from this dep, if you suffered 1, that's already pretty bad, being burnt twice should be a wake up call. If you get hit 3 times by the same dependency, it's a lost case.
As someone who does not use litellm but instead a barely maintained underpowered alternative: what did everyone migrate to?
If it matters, I am mostly interested in the aspect of having a proxy that unifies multiple ollama and openai-compatible endpoints with model-based routing and failover. Optionally with api-keys, reporting, budgets, etc. I do not particularly care about the MCP gateway, Agent-To-Agent thingy, and whatever else LiteLLM bolted on over time
After the last LiteLLM compromise, I took my requirement (an OpenAI compatible endpoint routing across multiple providers based on latency) and built that as a small static Rust binary - https://github.com/sturnus-dev/sturnus
Now that AI makes it cheaper to build such tools in-house, the case for adopting a maximalist framework and trusting that entire supply chain is a lot weaker.
Pydantic AI has a great set of abstractions over LLM providers. The documentation tends to focus on its agent loop more, but I find the LLM abstractions quite nice even on their own
IMHO defaults for uv, npm, etc should all have a cooldown for 24 - 48 hours by default, you should have to go out of your way to install something newer.
We have 7d cooldown on packages on an internal pypi proxy but that blocks security updates also, which we now have to manually exclude from the cooldown.
I’m unsure how to automate this properly, maybe an LLM is the best starting point.
They definitely wouldn't be if attackers knew that it would then bypass cooldowns!
Ultimately, you need someone to verify releases and that probably means paying for it. I know Sonatype paid solutions utilise their own internal research to allow/block new releases.
No, but there's a bigger tradeoff for not upgrading. In one case it's that you're potentially exposed to a known vulnerability, vs the other case where you might just be missing out on some new or slightly reworked feature.
I didn't realize they've all such added that, this was a change we made to our own projects last year when these first started - glad to see it's common.
Risk is ensuring enough security researchers are finding these and quarantining these before that default cooldown lapses.
Yea, I think all the tools have this now but its not a default. Install scripts should also be turned off by default and require some hassle to turn them on for the first time in a package.
I wonder if in some cases it's not so much that people are updating too quickly, but rather, their deployment pipelines do not have pinned / frozen versions attached to their builds.
Yes if you use LLM to analyse everything. Not really if you analyse diffs, with heuristics to select candidates for LLM/agent based analysis. But at the cost of missing out novel attacks.
I wish all the best to LiteLLM team with handling it again. I can imagine how challenging are situations like this one.
However, if anyone is looking for 20x faster and less "targeted" LiteLLM alternative - I'm work on one in Go. That's why GoModel it's called. https://github.com/ENTERPILOT/GoModel/
I myself have written a small llm proxy in Go, doing nothing but injecting the real API key to outgoing requests while itself validating virtual keys it generates, and it works great.
To clarify a little further, you can select the title, you just can't tell that it's selected because the author made a "poor" (REALLY REALLY DUMB) decision to deliberately style away a basic browser feature (text highlighting).
> There currently exists a private LiteLLM registry for enterprise customers, in which we are distributing an embargoed release that remediates a vulnerability whose disclosure date is scheduled for October 27.
oh boy. Announcing that there's a private enterprise repo you should be paying for if you don't want a credential stealer in your build is quite the optic, and then announcing there's an undisclosed second vulnerability that's being distributed, just not to the poors...
That's not what's being said, at all. They are simply telling their enterprise customers that there is a different build pathway for the enterprise builds and that pathway wasn't impacted by this issue.
Also if you don't like organizations fixing vulns without releasing the open source first, you're going to be upset when you learn how every major vuln and associated patches are distributed long before the fixes hit the repos. A timely example of this is PHP, literally today.
> A timely example of this is PHP, literally today.
Sorry, there was a paid-for PHP release that fixed it I could have gotten a week ago, and that they publicly announced existed, and it was just people who don't pay for PHP who had to wait...?
Yeah, that's how many companies with open ecosystems work. If you're using e.g. RedHat, you are getting packages with embargoed fixes baked into them before those fixes hit public repos. Node.js, OpenSSL, Git itself all do this.
You can argue about whether the "publicly announced existed" part since they don't advertise for any single package, but that's the ecosystem you buy into.
> If you're using e.g. RedHat, you are getting packages with embargoed fixes baked into them before those fixes hit public git repos.
The way you've written this is substantially misleading. RedHat receives notice of the vulnerabilities so they can prepare packages to be available the moment the embargo lifts, which I guess technically could hit the public packages a tiny bit earlier, but they are not releasing fixes of embargoed vulnerabilities to their commercial clients before the embargo lifts.
This is substantially different from the policy I've quoted that I am objecting to.

second? i haven't kept count, but we have to be somewhere in the hundreds of chances now

I use it, I don't cooldown, proper version pinning for me.
