Microsoft Entra Device Registration patches critical privilege escalation flaw
What happened.Microsoft released a security advisory addressing a maximum-severity authorization bypass vulnerability in Microsoft Entra Device Registration.
Why it matters.Modern enterprise security architectures rely on device registration services to establish trusted identity perimeters. When authorization checks accept untrusted cryptographic parameters during device enrollment, attackers bypass multi-factor conditional access controls and escalate privileges to global tenant administrators. Cloud security teams should review tenant audit logs for unauthorized device additions. Identity administrators must verify continuous device compliance evaluations across corporate directories.
