Authenticated privilege escalation via server-side request forgery
Published Dec 18, 2025 · Updated Dec 18, 2025
Server-side request forgery in Microsoft Azure Cognitive Service for Language allows remote authenticated users to elevate privileges over a network. Microsoft has not published the vulnerable request-processing locus, the accepted input, or how the service is induced to issue the forged request. Low-privileged service access is required; successful exploitation crosses a security boundary and can expose, alter, or interrupt resources reachable with the service's authority.
