Authenticated code execution via undisclosed code injection
Published Nov 14, 2023 · Updated Oct 8, 2025
Code injection in Microsoft Azure Pipelines Agent before 2.39.1 allows remote authenticated users to execute arbitrary code over a network. Microsoft identifies improper control over generated code but has not disclosed the affected component or how attacker-controlled input reaches code generation. Exploitation requires low-privileged authentication and no user interaction, and successful execution can read or modify data and interrupt the agent service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
