Microsoft on Thursday warned of a maximum-severity security flaw in Entra ID that it said has been exploited in the wild, but noted that no customer action is required.<\/p>\n

The vulnerability, tracked as CVE-2026-69836<\/strong> (CVSS score: 10.0), is a case of remote code execution impacting the tech giant’s cloud-based identity and access management service. It was previously called Azure Active Directory or Azure AD.<\/p>\n

\u00abDeserialization of untrusted data in Microsoft Entra ID allows an unauthorized attacker to execute code over a network,\u00bb Microsoft said<\/a> in an alert released Thursday.<\/p>\n

Flaws of this kind<\/a> occur when an application converts user-controlled data back into an active object or code structure without proper validation. This can lead to<\/a> code execution, denial-of-service, or access control bypass that can permit an attacker to perform unauthorized actions.<\/p>\n

The company credited Principal Security Engineer Robert Fitzaptrick for discovering and reporting the issue.<\/p>\n

As of writing, there are currently no details on how the vulnerability has been exploited, when these efforts began and if they are still ongoing, and how it was discovered.<\/p>\n

\u00abThis vulnerability has already been fully mitigated by Microsoft,\u00bb it added. \u00abThere is no action for users of this service to take.\u00bb<\/p>\n

Earlier this month, Redmond also patched a high-severity security privilege escalation flaw affecting Windows Ancillary Function Driver for WinSock (CVE-2026-68820, CVSS score: 7.0) that was exploited as a zero-day by the North Korea-linked Lazarus Group as part of a long-running campaign dubbed Operation Dream Job.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
