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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-400","CWE-835"],"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-jj5r-9rpc-8h6h","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-jj5r-9rpc-8h6h","tags":[]}],"hasPoc":true,"ai":null}
