CVE-2026-69836 Aug 20, 21:43 CRITICAL POC KEV PATCH THREAT NEWS Exploited Act Now

Remote code execution in Microsoft Entra ID lets an unauthenticated network attacker run arbitrary code by submitting maliciously crafted serialized data that the service deserializes without validation (CWE-502). The CVSS 3.1 base score is a maximum 10.0 with a scope change, reflecting unauthenticated network reach and full compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the combination of a cloud identity platform and PR:N/UI:N makes this an urgent-patch candidate.

CVE-2026-69851 Aug 20, 21:43 CRITICAL PATCH Act Now

Privilege elevation in Microsoft Entra ID (formerly Azure Active Directory) allows an authenticated, low-privileged attacker to abuse a server-side request forgery flaw (CWE-918) to reach protected internal endpoints and escalate privileges across a security scope over the network. The flaw carries a critical CVSS 9.9 with a scope change, meaning a foothold in one context can be leveraged to compromise resources beyond the attacker's original authorization. Microsoft has issued a service-side fix; there is no public exploit identified at time of analysis and no CISA KEV listing.

CVE-2026-42901 May 22, 22:04 CRITICAL PATCH NO ACTION HOSTED Monitor

Privilege escalation in Microsoft Entra ID enables remote unauthenticated attackers to bypass origin validation and gain elevated privileges across tenant boundaries (scope-changed). The CVSS 10.0 rating reflects maximum impact across confidentiality, integrity, and availability with no authentication or user interaction required, though no public exploit has been identified at time of analysis and EPSS data is not provided.

CVE-2026-33843 May 22, 22:03 CRITICAL PATCH NO ACTION HOSTED Monitor

Privilege elevation in Microsoft Azure Active Directory B2C (now part of Microsoft Entra) lets a remote, unauthenticated attacker bypass authentication by abusing an alternate path or channel and gain elevated access over the network. Any tenant relying on Entra/Azure AD B2C for customer-facing identity is affected until Microsoft's cloud-side fix is applied or automatically rolled out. There is no public exploit identified at time of analysis, and EPSS rates near-term exploitation probability very low (0.05%), but SSVC flags the technical impact as total and the flaw as automatable.

CVE-2026-35431 Apr 23, 21:37 CRITICAL PATCH NEWS NO ACTION HOSTED Monitor

Server-side request forgery in Microsoft Entra ID Entitlement Management lets a remote, unauthenticated attacker coerce the cloud service into making attacker-directed requests, enabling spoofing and full compromise of confidentiality, integrity, and availability across a security-scope boundary (CVSS 10.0). No public exploit identified at time of analysis and EPSS is low (0.07%), but the SSVC framework flags the flaw as automatable with total technical impact. As a cloud-hosted Microsoft identity service, remediation is delivered by the vendor rather than by customer patching.
