CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
