ANSSI (the French national cybersecurity agency) issued an advisory regarding a vulnerability in Microsoft Entra ID that allows an attacker to achieve remote code execution. Microsoft has confirmed that the flaw, tracked as CVE-2026-69836, is being actively exploited in the wild, though the advisory does not provide technical details on the exploitation method or observed threat actors.
Given Entra ID's central role as Microsoft's cloud identity and access management platform, a remote code execution vulnerability affecting it poses significant risk to organizations relying on it for authentication and identity federation. ANSSI directs affected organizations to Microsoft's security bulletin for patching guidance. Defenders should prioritize applying the vendor's fix immediately given the confirmed active exploitation, and review Entra ID sign-in and audit logs for anomalous administrative or application activity as a precaution.
