CVE-2026-32211: Microsoft Azure MCP Server missing authentication in Azure Web Apps

CVE-2026-32211 · Severity: critical · CVSS 9.1 · Published 2026-04-03

A security flaw in the Microsoft Azure MCP Server, a component used within Azure Web Apps, allows unauthorized individuals to access sensitive information.

Technical details

A vulnerability classified as Missing Authentication for Critical Function (CWE-306) exists in the Azure MCP Server component of Azure Web Apps. The flaw allows an unauthenticated remote attacker to invoke sensitive functions over the network without providing credentials. Successful exploitation enables the attacker to disclose sensitive information and potentially impact data integrity. Microsoft has assigned a CVSS score of 9.1, reflecting the high impact on confidentiality and integrity and the lack of required privileges or user interaction. As this is an exclusively hosted service, Microsoft typically manages the remediation on the backend.
