CVE-2026-73294
Last modified
CVE-2026-73294 is a critical-severity vulnerability rated 9.9/10 on the CVSS scale. Semaphore UI is a web interface for managing DevOps tools. Prior to 2.18.17 and 2.19.5-beta2, repository git_url handling passes an attacker-controlled --upload-pack option to CmdGitClient.GetLastRemoteCommitHash through POST /api/project/{id}/repositories and scheduled commit-hash polling, allowing a project Manager or Owner to execute arbitrary OS commands in the Semaphore server process. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
