Description
AI Translation Available
Semaphore versions prior to 2.18.20 contain an OS command injection (argument injection) vulnerability in the repository git_url handling that allows authenticated users holding the Manager or Owner role on any project to achieve remote code execution on the Semaphore server host. Attackers can craft a malicious git_url value using git's --upload-pack= option to inject and execute arbitrary shell commands when the server processes repository operations using the default cmd_git client.
