{"id":"CVE-2026-70402","summary":"Gitea local code execution through writable Git hooks","details":"Gitea creates server-side Git hook directories and scripts with mode 0777 and relies on the process umask to restrict access. With a permissive umask such as 0000 or 0002, another local user who can reach the repository storage may modify a hook or add an executable to a writable hook directory. A later Git operation can execute that file as the Gitea service account.","aliases":["GHSA-pq8x-xpgp-rvmh"],"modified":"2026-10-16T02:47:43.715183444Z","published":"2026-10-14T14:36:46.774Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70402.json","cna_assigner":"Gitea","cwe_ids":["CWE-732"]},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.3/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70402.json"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-pq8x-xpgp-rvmh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70402"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39008"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39016"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"fixed":"146cc3eec57174711eac0e0a0c7b38670c6e3922"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"1.27.2"}]}}],"versions":["v1.27.2","v1.27.1","v1.27.0","v1.27.0-rc0","v1.28.0-dev","v1.27.0-dev","v1.26.0-dev","v1.25.0-dev","v1.24.0-dev","v1.22.0-rc1","v1.23.0-dev","v1.22.0-rc0","v1.21.0-rc0","v1.22.0-dev","v1.20.0-rc0","v1.21.0-dev","v1.20.0-dev","v1.19.0-rc0","v1.18.0-rc0","v1.19.0-dev","v1.18.0-dev","v1.17.0-dev","v1.16.0-rc1","v1.15.0-rc1","v1.16.0-dev","v1.15.0-dev","v1.14.0-dev","v1.13.0-dev","v1.12.0-dev","v1.10.5","v1.11.0-rc1","v1.10.0-rc1","v1.11.0-dev","v1.9.0-rc1","v1.10.0-dev","v1.9.0-dev","v1.7.0-dev","v1.6.0-rc1","v1.6.0-dev","v1.5.0-rc1","v1.5.0-dev","v1.1.0","v1.0.0","v0.9.99"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-70402.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:L"}]}
