🔴 Critical: Microsoft Patches Severe Entra ID Flaw (CVSS 10.0) Allowing Remote Code Execution
-
Microsoft has released a patch for a critical vulnerability in Entra ID that carries the maximum CVSS score of 10.0, making it one of the most severe flaws addressed in the company’s latest update cycle. The issue, if exploited, could allow an attacker to achieve remote code execution against affected systems.
The flaw was initially flagged in Microsoft’s security bulletin with the "Exploited" field marked as "Yes" under the Exploitability Assessment table. However, after The Hacker News reached out for clarification, Microsoft revised the status on August 21, 2026, confirming that the vulnerability has not been exploited in the wild. The company also emphasized in its update that this vulnerability was not leveraged in any known attacks.
- Affected component: Entra ID (formerly Azure Active Directory)
- Severity rating: CVSS 10.0 (Critical)
- Attack vector: Remote code execution
Given the severity of the flaw, administrators are strongly advised to apply the latest patches immediately, even though there is no current evidence of active exploitation. The correction in the bulletin should not diminish the urgency of updating, as the potential impact remains severe.
