CVE-2026-45499Network attack vector

Authenticated privilege elevation via server-side request forgery

Published Jul 2, 2026 · Updated Jul 2, 2026

Server-side request forgery in Microsoft Azure OpenAI allows remote authenticated users to elevate privileges through service API requests. Microsoft has not published the affected API operation, controllable URL field, or server-side request validation failure that enables the SSRF. A valid Azure OpenAI API key or Microsoft Entra token is required; successful exploitation grants privileges beyond the caller's assigned authority.
