Open AI Model Turned Firefox Fixes Into Working Attacks

Research group Epoch AI reports that GLM 5.3, a widely available AI model, turned public Firefox security fixes into working attacks. It compromised six Firefox releases in under 48 hours, at roughly $1,000 per release, with no human input and without tripping safeguards. The finding suggests users may be exposed before updates reach them.
