{"id":"BIT-gitea-2026-104633","summary":"Gitea migration memory exhaustion from zero page size","details":"When migrating a repository from another Gitea instance, Gitea used the page size reported in the source server's API settings to end its paginated downloads. 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.","aliases":["CVE-2026-104633","GHSA-jj5r-9rpc-8h6h"],"modified":"2026-10-14T11:10:52.032645864Z","published":"2026-10-14T08:42:40.149Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:gitea:gitea:*:*:*:*:*:*:*:*"]},"references":[{"type":"ARTICLE","url":"https://blog.gitea.com/release-of-28.1.0/"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39501"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39507"},{"type":"ARTICLE","url":"https://github.com/go-gitea/gitea/releases/tag/v28.1.0"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-jj5r-9rpc-8h6h"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104633"}],"affected":[{"package":{"name":"gitea","ecosystem":"Bitnami","purl":"pkg:bitnami/gitea"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"28.1.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/gitea/BIT-gitea-2026-104633.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
