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.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104633","source_modified_at":"2026-10-07T15:53:48.550Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Gitea","vendor":"Gitea","versions":[{"version":"0","status":"affected","lessThanOrEqual":"28.0.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00397,"percentile":0.3278,"score_date":"2026-10-23"},"published_at":"2026-10-06T21:35:26.516Z","modified_at":"2026-10-07T15:53:48.550Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104633","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T15:53:48.550Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104633","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-jj5r-9rpc-8h6h","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39501","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39507","tags":["patch"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-28.1.0/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v28.1.0","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-07T15:51:08.820853Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T15:53:48.550Z","content_hash":"9eec6ef0c6d7e862d39d961b0fed4634cc66e01e9ef656a65e8ff67168cc92d6"}}
