tl;dr: Microsoft patched 570 vulnerabilities this Patch Tuesday—nearly triple last month's record—including 60 critical bugs and three zero-days, two of which are being actively exploited. Microsoft attributes the surge to AI-assisted vulnerability discovery, a trend echoed by Adobe, Cisco, Mozilla, Oracle, and Google ramping up their own patch cadences. Researchers warn that Microsoft's human-centric "exploitability index" is falling behind, as AI tools like Anthropic's red team model have produced working exploits for 13 of 14 flaws rated "less likely" to be exploited.
