Security experts attribute the unprecedented volume to AI-assisted vulnerability discovery, with Tenable projecting Microsoft could surpass 3,000 CVEs for the full year. Anthropic's Red Team findings show AI can generate proof-of-concept exploits for vulnerabilities previously rated as unlikely to be exploited, undermining the traditional Exploitability Index. Experts urge immediate patching of the AD FS and SharePoint flaws, a 9.9 CVSS VMSwitch VM-escape bug, and critical RCE vulnerabilities in Active Directory Domain Services, Exchange Server, and SQL Server. SAP also released 20 patches, headlined by a 9.9 CVSS memory corruption flaw in NetWeaver AS ABAP. Industry voices are calling for a shift from monthly patch cycles to continuous, adaptive patching to keep pace with AI-accelerated discovery and exploitation. ## Full article daily.dev links to this article rather than hosting it.
