This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. CVE-2026-73294 published by GitHub
No vendor fix or workaround currently provided.
OpenCVE Recommended Actions
- Update Semaphore to version 2.18.20 or later to remove the vulnerable git_url processing logic.
- If an immediate upgrade is not possible, restrict the git_url input to only allow safe, unsigned patterns or block use of the --upload-pack option entirely, thereby preventing command injection.
- Implement or enforce stricter validation and sanitization on the git_url field to reject any URLs containing shell metacharacters or git plumbing options such as --upload-pack.

| Description | 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. | This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
