A collaborator with Code write access and without Releases write access could permanently delete published releases of that repository, including their attachments. Protected tag rules covering the release tag still blocked the deletion.","published":"2026-10-06T22:17:02.000Z","lastModified":"2026-10-13T14:38:48.000Z","status":"Analyzed","sourceIdentifier":"88ee5874-cf24-4952-aea0-31affedb7ff2","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},"cwe":["CWE-732","CWE-863"],"affected":["gitea/gitea"],"epss":{"score":0.00378,"percentile":0.31551,"date":"2026-10-26","history":[{"date":"2026-10-07","score":0.00173,"percentile":0.06108}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.38%).
