Yikes, Schemata and that delinquent CEO should be held accountable.

Would it be possible to stop using aXXb nomenclature within the titles? Some of us aren't hip enough to know what all of them mean.

a16z = "Andreessen Horowitz", for those not in the know. (The acronym is not expanded in the article. EDIT: OP has fixed the article.)

> Their initial reply from the CEO: "I would love to hear what the vulnerability is, but I assume you want to get paid for it. Is that the play?"

Well that’s pretty damning.

Finally the AI security startup hustlers will keep the other tech startup hustlers in line. Maybe the era of devastating leaks and total disregard for user privacy will come to an end (doubtful).

"There was no meaningful organization scoping, no tenant isolation, and no permission check preventing a low-privilege user from accessing other organizations' records."

Let me guess though. They are SOC2 and ISO compliant right ?

I wonder if this is how Handala group stole the list of service members recently.

How do people find these vulnerabilities within the immense scope of the whole internet? Are they going around with some kind of generic API scanner that discovers APIs?

Initial take: as vulnerability stories go, this is a pretty boring one; what they have here is a target that was secured largely by the fact that few people knew about it. The most work done in this blog post is establishing that a training platform deployed by DoD might be much more sensitive than the same kinds of applications which are ubiquitous throughout corporate America and which are generally boring targets.

The vulnerability itself appears to be something anyone with mitmproxy would have spotted within minutes of looking at the platform; apparently, rotating object IDs worked everywhere in the app, and there was no meaningful authz.

It's interesting if AI systems can "spot" these, in the sense of autonomously exercising the application and "understanding" obvious failed authz check patterns. But it's a "hm, ok, sure" kind of interesting.
