Authenticated data disclosure via server-side request forgery
Published Feb 10, 2026 · Updated Feb 10, 2026
Server-side request forgery in Microsoft Azure DevOps Server 2022 before 20260204.3 allows remote authenticated users to read sensitive data. Microsoft has not published the affected request handler or how attacker-controlled input selects a server-side destination. Low-privileged network access is required; successful exploitation exposes confidential data without a reported integrity or availability effect.
