Microsoft attributes the surge to AI-assisted vulnerability discovery. Notable CVEs include elevation-of-privilege zero-days in Active Directory Federation Services and SharePoint, a BitLocker security bypass, and a remote code execution flaw in Microsoft Copilot (CVSS 9.6). Security researchers warn that Microsoft's exploitability index is outdated in the AI era, as Anthropic's red team model generated working exploits for 13 of 14 vulnerabilities rated 'less likely' to be exploited. Adobe, Cisco, Mozilla, Oracle, and Google are also accelerating patch cadences, citing AI-driven discovery. Users are advised to wait a few days before applying patches given the volume and risk of stability issues. ## Full article daily.dev links to this article rather than hosting it.
