SSRF in Microsoft Entra ID Entitlement Management

IdentifiersCVE-2026-35431CWE-918· Server-Side Request Forgery (SSRF)

CVE-2026-35431 is a server-side request forgery (SSRF) vulnerability in Microsoft Entra ID Entitlement Management. According to Microsoft, the flaw allows an unauthorized attacker to perform spoofing over a network. Publicly available information indicates the vulnerable service could be induced to make server-side requests to unintended destinations, consistent with SSRF behavior. Microsoft assigned CVSS v3.1 AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H (base score 10.0), indicating remote exploitation with no privileges or user interaction and potential impact beyond the vulnerable component’s security boundary. Public disclosures do not provide the exact vulnerable function, request path, or tenant-specific triggering conditions.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation could allow an unauthenticated remote attacker to coerce the Microsoft Entra ID Entitlement Management service into making unintended server-side requests, enabling spoofing and potentially interaction with internal or otherwise restricted services. Based on Microsoft’s CVSS assessment and advisory context, the resulting impact may extend beyond the vulnerable component and could include high-impact effects on confidentiality, integrity, and availability, such as access to sensitive data, manipulation of response integrity, or disruption of service behavior.

Mitigation

If you can’t patch tonight, do this now.

No customer mitigation steps are required. Microsoft states the issue has already been fully mitigated by Microsoft in the hosted service.

Remediation

Patch, then assume compromise.

No customer remediation is required. Microsoft states the vulnerability was fully remediated on the server side on April 23, 2026. Because Microsoft Entra ID Entitlement Management is a fully managed cloud service, there is no downloadable patch, KB article, or tenant-side configuration change for customers to apply.
