A low-privileged user who can create migrations or mirrors could direct the server to internal services, reading from and writing to reachable internal Git or HTTP endpoints. Content from internal responses could additionally be disclosed through migration and mirror error messages.","published":"2026-10-06T20:17:09.000Z","lastModified":"2026-10-15T02:29:41.000Z","status":"Analyzed","sourceIdentifier":"88ee5874-cf24-4952-aea0-31affedb7ff2","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-209","CWE-367","CWE-918"],"affected":["gitea/gitea"],"epss":{"score":0.00179,"percentile":0.07407,"date":"2026-10-27","history":[{"date":"2026-10-07","score":0.00124,"percentile":0.01874}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.18%).
