GPT-6 Cyber finds 81 Firefox flaws
OpenAI’s GPT-6 Cyber produced evidence and reproducible tests for 81 novel Firefox vulnerabilities that Mozilla rated high severity, while flagging 30 known issues as more serious than previously reported. The findings included proposed patches, and Mozilla began landing fixes shortly after disclosure.
// ANALYSIS
GPT-6 Cyber signals a shift from AI-assisted code review toward autonomous vulnerability research. Its value lies not just in finding bugs, but in producing actionable exploit evidence and patches under authorized workflows.
- –Mozilla’s results show frontier models can uncover deep, high-severity issues in heavily scrutinized software.
- –Reproducible tests and proposed fixes make the output substantially more useful than noisy automated scanning.
- –OpenAI reports a 48.5% ExploitGym score, up from 32.1% for GPT-5.6 Cyber.
- –Restricted Daybreak Red access reflects the operational risk of a model capable of exploit development.
- –Developers will need stronger sandboxing, authorization, disclosure, and patch-gap controls as cyber models improve.
