{"id":"CVE-2026-96594","summary":"Gitea repository media API stored XSS","details":"The Gitea API endpoint `GET /api/v1/repos/{owner}/{repo}/media/{filepath}` wrote files of up to 1 KiB that are stored directly in Git, not in LFS, to the response without the content type and disposition headers Gitea uses for user content. An HTML file committed to a repository was therefore rendered by the browser on the Gitea origin. A user who can push to a repository could run JavaScript in the session of a victim who opens the media URL and act with the victim's permissions.","aliases":["BIT-gitea-2026-96594","GHSA-94rx-fqm6-q23v"],"modified":"2026-10-24T10:32:55.550040522Z","published":"2026-10-06T21:36:38.491Z","database_specific":{"cna_assigner":"Gitea","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/96xxx/CVE-2026-96594.json"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-28.1.0/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/96xxx/CVE-2026-96594.json"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v28.1.0"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-94rx-fqm6-q23v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-96594"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39501"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39507"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"fixed":"4ebd5e319b6a9e629bfd7a04292a6fe85b08dee9"}],"database_specific":{"extracted_events":[{"cpe":"cpe:2.3:a:gitea:gitea:*:*:*:*:*:*:*:*","range":[{"introduced":"0"},{"fixed":"28.1.0"}],"source":"CPE_RANGE"},{"original_tag":"v28.1.0","range":[{"fixed":"4ebd5e319b6a9e629bfd7a04292a6fe85b08dee9"}],"source":"REFERENCES_TAG"}]}}],"versions":["v28.0.0","v29.0.0-dev","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/osv-test-cve-osv-conversion/osv-output/CVE-2026-96594.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
