CVE-2026-96594

Gitea repository media API stored XSS

Published Oct 6, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed
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.
