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.","published":"2026-08-14T21:17:58.033","modified":"2026-08-14T21:17:58.033","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/semaphoreui/semaphore/commit/5d87656a680600125fe78edec1f7a0d10484b52c","label":"semaphoreui/semaphore@5d87656"},"references":[{"type":"WEB","url":"https://github.com/semaphoreui/semaphore"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/commit/5d87656a680600125fe78edec1f7a0d10484b52c"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/security/advisories/GHSA-xp7j-h7jc-4w8p"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/security/advisories/GHSA-xp7j-h7jc-4w8p"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/semaphore-prior-to-version-os-command-injection-via-git-url-repository-handling"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T21:17:58.033"}}
