A source that reported `max_response_items` as `0` made these loops run indefinitely and grow server memory until it was exhausted. Any user who can migrate repositories could point a migration at a server they control and cause a denial of service.","published":"2026-10-06T22:17:01.000Z","lastModified":"2026-10-13T14:38:56.000Z","status":"Analyzed","sourceIdentifier":"88ee5874-cf24-4952-aea0-31affedb7ff2","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-400","CWE-835"],"affected":["gitea/gitea"],"epss":{"score":0.00397,"percentile":0.33692,"date":"2026-10-26","history":[{"date":"2026-10-07","score":0.00168,"percentile":0.05498}]},"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 (0.40%).
