{"id":"CVE-2026-66849","summary":"Gitea restricted-user package visibility bypass","details":"Gitea's package registry grants authenticated users read access to packages owned by Limited-visibility users without excluding restricted accounts. A restricted user can enumerate and download those packages despite the visibility policy that should prevent this access. The issue affects user-owned package registries and exposes package contents across the intended authorization boundary.","aliases":["GHSA-px3q-x2mm-55wg"],"modified":"2026-10-16T02:48:06.227862946Z","published":"2026-10-14T14:35:55.956Z","database_specific":{"cwe_ids":["CWE-284"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/66xxx/CVE-2026-66849.json","cna_assigner":"Gitea"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.3/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/66xxx/CVE-2026-66849.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-px3q-x2mm-55wg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66849"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39043"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39058"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"fixed":"146cc3eec57174711eac0e0a0c7b38670c6e3922"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.27.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"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-2026-66849.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:L/I:N/A:N"}]}
