CVE-2024-20667Network attack vector

Authenticated code execution via command injection

Published Feb 13, 2024 · Updated Aug 10, 2026

Command injection in Microsoft Azure DevOps Server allows remote authenticated users to execute code through crafted network requests. Microsoft identifies CWE-77 but has not disclosed the affected component, request field, or command-building operation. Exploitation requires valid low-privilege credentials and high-complexity conditions; successful attacks execute code with the server process's authority.
