Entra ID Agent Role Flaw Allows Service Principal Takeover, Patch Deployed
A built-in Entra ID role called Agent ID Administrator could let attackers take ownership of arbitrary service principals, enabling privilege escalation and potential tenant compromise. Microsoft issued a patch across cloud environments on April 9 to block ownership changes by the Agent ID Administrator on non-agent principals, mitigating the risk. Security researchers urge ongoing monitoring of sensitive role usage, ownership changes, secure handling of privileged service principals, and auditing credential creation on service principals to reduce exposure from this loophole.
