ameliaquining | on: Tracking Anthropic-discovered vulnerabilities
Claude is perfectly capable of fixing most vulnerabilities; if that's what maintainers want, they can just ask for it. If the concern is cost, Anthropic offers a Claude for OSS program.

The reason Anthropic isn't proactively sending patches is, I suspect, that those patches would not be welcomed, because trust in the models isn't currently at the point where maintainers are willing to merge them without human review, which takes approximately as much effort as writing the patches themselves. You can imagine the wailing and gnashing of teeth about "slop PRs" and "extractive contributions" that'd be all over HN.

Anthropic's oss-scanner includes patches. We've received a batch and I'm working on some of it.

A good amount of the patches is straight garbage. It's not helped by the fact that a good amount (20~30%, maybe more) of the issues is also junk themselves.

I'll hopefully be able to share numbers (or data) after we're done with the batch.

I won't claim that my experience is representative, but what I've seen is closer to 50% being false positives, and then maybe 20% of the remainder being bugs but not vulnerabilities (aka lower priority bugfixes). The suggested patches have a much worse hit rate though, to the extent that I accepted only a small fraction after reviewing.

That said, an automated system generating only 30% true positives is probably still ahead on ROI as long as we're talking about tens of findings and not hundreds. The amount of human time spent investigating things that turn out to be false positives being the main difference for how over or underwhelming it is.

Yeah, I was being "optimistic" in my estimate. And of course with a batch, you start at the high severity end, so it gets worse as you progress through. (Well, I assume at least, even some of the "critical" was just plain "not even a security issue" in our case.)

70-80% not being garbage sounds like a good thing :)

You're assuming the other 70-80% is actually good. It's not, there's a whole spectrum between "junk" and "good". A whole bunch of this stuff is "technically correct, technically even a security issue, but also just plainly not of actual importance".

I suppose it depends on:

- How many patches you receive

- How easy it is/long it takes to distinguish the good from the garbage

thanks! It turns out that I am apparently qualifying for it and I was unaware

lets see whether Anthropic agrees
