Comment on Mozilla Used Anthropic's Mythos to Find and Fix 271 Bugs in Firefox

Comments

So where are they, then? Am I misunderstanding the process and this stuff is kept under wraps even after release?

There's three CVEs in today's security advisory that mention Anthropic.

There's also no write-up I can see that distinguishes to what extent this is the work of the seven people credited alongside Mythos.

Last three CVEs are collections of bugs. CVE-2026-6784 is a collection of 55 bugs. CVE-2026-6785 is a collection of 154 bugs. CVE-2026-6786 is a collection of 107 bugs.

As for credits, I think bugs are ultimately credited to people, and this time Mozilla people used Mythos, as opposed to Anthropic people using Opus or Mythos.
