Entra ID under fire as critical RCE was already actively exploited
Microsoft confirms that CVE-2026-69836, a critical RCE vulnerability in Entra ID, has been actively exploited by attackers.
The flaw enabled remote code execution without authentication or user interaction via insecure deserialization.
As Entra ID is central to Microsoft 365, Azure, and SSO, exploitation could potentially grant access to tokens, policies, and linked cloud environments.
Microsoft has since resolved the issue server-side; customers do not need to patch, but are advised to check sign-in logs, privileged roles, and Conditional Access for anomalies.
