ExploitsActive Zero-Day Alert: Microsoft Confirms Exploitation of CVSS 10.0 Entra ID Flaw Prior to Patch
On Thursday, Microsoft revealed that a critical remote code execution (RCE) vulnerability in Entra ID—the identity engine powering Microsoft 365, Azure, and Dynamics 365—was actively exploited in the wild prior to server-side mitigations. Tracked as CVE-2026-69836 and assigned a maximum CVSS score of 10.0, the flaw allows unauthenticated remote code execution. While Microsoft has patched the infrastructure, the lack of published indicators of compromise (IOCs) leaves enterprise defenders
