Privilege escalation via pipeline job tokens
Published Mar 12, 2020 · Updated Aug 4, 2024
An elevation of privilege flaw in Microsoft Azure DevOps Server allows remote authenticated users to gain higher privileges through pipeline job tokens. The server improperly handles tokens issued to pipeline jobs, allowing a job token to carry authority beyond the intended security boundary. Exploitation requires authenticated pipeline access, and the resulting privilege increase can expose or modify DevOps resources available to the token.
