well done all around. i think my only open question is what default security boundaries should all vibecoded internal agents follow as a learning we can take from this
Good in terms of prompt communication and fix. Absurdly bad in terms of reward.
Earlier in the article, it mentions that Baseten is valued at $13B. They can't dig into their couch cushions to give a few thousand dollars to the researcher privately disclosing a bug that let an attacker escalate to admin in their GitHub org?
This sends the message that honest researchers should not waste their time looking for vulnerabilities in Baseten, but it's a good target for criminals who want to monetize these vulnerabilities.
Yeah companies need to quickly understand that having good actors try and hack you is a good thing - those hacks get reported and another door gets sealed shut for bad actors.
This is more true today than ever before as the bar for a successful attack has never been lower. We’ll see a resurgence of the script-kiddie, or shall I say, vibe-kiddie :-/
> [pen-testing agent] came back with an active GitHub personal access token for basetenbot. That token had admin and push access to Baseten's main product repo, the GitOps repo that drives their clusters, and their Homebrew tap, plus read/write access to other private repositories including specific repos per customers.
And the agent found the token in Docker build history after finding a Baseten image repository.
I wonder how many of these kinds of agent-driven security exploits we're not hearing about these days (i.e. driven by bad actors), worrying.
That is great marketing for strix, pretty bad for baseten.
I don't think someone can have a better story to advertise their own security product.
Did not know about strix but I am going to look it up now.
Might add it to my stack.
Yeah I have seen this issue a few times. If you use Docker build arguments that way add `--provenance=false` to get rid of all that build metadata. Build secrets are still better since they allow you to scope the secret inside of the Dockerfile. Also, the metadata can be useful to inspect images.
Baseten carries the Soc 2 Type II and HIPAA Compliant logos on its front page. They also have logos for customers including: OpenEvidence (medical related, used by almost 2/3 of physicians in the US, claim HIPAA compliance), Harvey (legal related, claim "binding terms on data protection, data access, incident response SLAs, and other controls aligned with SOC2, ISO, GDPR and other standards.")

Given the build is from 2023 one would expect that at least the token would have been rotated, and I suspect some of these compliance checks do require rotation of tokens/passwords.
That said, the whole compliance industry is a joke.
1. A start up is validating a service provider to ensure that they are secure enough so that they can trust them before signing up for their service
2. The service provider is already trusted by so many big name companies who handed over their data, the customers data to them
Should it not be other way around?
On a different note, the finding is not just one off absolute, rather its a symptom which points to certain experience and expertise level for security practices. To be fair its hard to blame the start up folks, they are running against time and cutting corners is somewhat critical for survival for their business
i quite liked using strix. last time i tried it, deepseek was a mess and bloated the context with nonsense. that was ~5 months ago, i wonder how it performs now

Honestly I would have held out for a (hard to get) hardcover copy of Inference Engineering.

lawyers wet dream. and a perfect case. A security company who KNOWS the law unleashed an AI agent to violate the laws
Now if only we knew if the stonks would go up or down (due to global turmoil) before I throw my savings at the SPY
I get how these choices might be the local optimum for a desired UX, but damn is it depressing to extrapolate where software as a whole is going.
Kudos for Strix to find it, and especially with how it chose to disclose and report it.

What are the legal implications here?
