What happened
A cluster of high-risk events and research highlights dominated the feed: AI-powered bug-hunters (Anthropic’s Mythos and Claude variants) are rapidly surfacing large numbers of flaws (e.g., 271 Firefox issues) while researchers and attackers are already using models to develop exploits (Claude Opus Chrome exploit, Git identity spoofing to bypass AI code review). Multiple actively exploited and urgent vulnerabilities were reported — Cisco Catalyst SD‑WAN Manager bugs under attack (4‑day CISA patch directive) and a long‑standing Apache ActiveMQ flaw added to KEV (two‑week federal patch order).
