Anthropic leveraged its Claude Opus 4.6 model to scan Firefox source code and identify 22 security vulnerabilities—14 of them high severity—which Mozilla fixed in Firefox 148; the team also attempted automated exploit development and produced crude, controlled-environment exploits in two cases, highlighting both AI-assisted discovery power and the limited current risk of automated exploitation.
