In other words: AI is making it possible to detect severe security vulnerabilities at highly accelerated speeds,” Anthropic said.
Firefox's real-world security defenses would have blocked both of them, according to Logan Graham, who leads Anthropic's Frontier Red Team — the group that tests Claude for potential risks.
Mozilla confirmed that Claude had uncovered more high-severity flaws in that short period than the entire global security research community typically reports in two months, the report claimed.“ Claude Opus 4.6 discover…

over a mere two-week span, Anthropic’s latest model, Claude Opus 4.6, uncovered 22 distinct vulnerabilities within the Firefox codebase.
It had scanned almost 6,000 C++ files and made more than 100 different reports for Mozilla to look at.
Claude found a “use-after-free” bug in the browser’s JavaScript engine in less than 20 minutes.

How score signals are formed
Bias score signalBias signal combines framing pressure, emotional wording, selective emphasis, and one-sided narrative markers.
Emotionality signalEmotionality rises when evidence contains emotionally loaded wording and evaluative labels.
One-sidedness signalOne-sidedness rises when one frame dominates and alternative interpretations are weakly represented.
Evidence strength signalEvidence strength rises with concrete claims, attributed statements, and verifiable contextual support.
