{"id":"CVE-2026-96594","published":"2026-10-06T22:17:07.810","lastModified":"2026-10-07T16:19:13.213","description":"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.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-28.1.0/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39501","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39507","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.1.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-94rx-fqm6-q23v","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/39501","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39507","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.1.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-94rx-fqm6-q23v","tags":[]}],"hasPoc":true,"ai":null}
