CVE-2026-58630 Jul 24, 14:36 CRITICAL PATCH HOSTED Monitor

Privilege escalation in Microsoft Azure App Service for Linux lets a remote, unauthenticated attacker bypass access controls and gain elevated privileges over the network, per Microsoft's MSRC advisory and a CVSS 9.8 rating. Because the underlying weakness is improper access control (CWE-284), a successful attack yields total confidentiality, integrity, and availability impact on the affected app-hosting environment. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, though CISA's SSVC assessment flags the flaw as automatable with total technical impact, and the modest EPSS score (0.81%) reflects an as-yet-unproven-but-realistic exploitation path.
