{"id":"CVE-2026-73814","summary":"Gitea repository ownership escalation by administrators","details":"Gitea's collaboration access-mode endpoint accepts the Owner access mode from an authenticated repository collaborator with Admin access. The collaborator can promote their effective permissions from Admin to Owner and then perform owner-only operations, including transferring the repository to their own account. This bypasses the intended boundary between repository administration and ownership.","aliases":["GHSA-h62v-wmrr-5qjq"],"modified":"2026-10-15T02:47:44.036267277Z","published":"2026-10-14T14:38:05.476Z","database_specific":{"cna_assigner":"Gitea","cwe_ids":["CWE-266"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73814.json"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.2/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73814.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/38894"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/38895"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-h62v-wmrr-5qjq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73814"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"last_affected":"a62dfffbe7d3a454c2f2d3c4b2788ba432724a5f"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"1.27.1"}]}}],"versions":["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-2026-73814.json"}}],"schema_version":"1.9.0"}
