{"schema":"threatline.record/2","record":{"id":"CVE-2026-73273","aliases":["GHSA-5xcq-p92v-43rf"],"summary":"Gitea Maven checksum upload quota bypass and memory exhaustion","details":"Gitea's Maven upload handler reads checksum uploads entirely into memory and returns before enforcing package-size quotas. An authenticated user with package-publish permission can submit an oversized body to a checksum endpoint despite legitimate checksum values being at most 128 bytes. This bypasses the upload quota on that path and can exhaust server memory.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-73273","source_modified_at":"2026-10-14T15:03:16.838Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Gitea","vendor":"Gitea","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.27.2","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00389,"percentile":0.31855,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:37:30.614Z","modified_at":"2026-10-14T15:03:16.838Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-73273","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T15:03:16.838Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-73273","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-5xcq-p92v-43rf","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-1.27.3/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39028","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39031","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","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":"2026-10-14T14:43:29.972852Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T15:03:16.838Z","content_hash":"9092d1525e7ab1912c3c790ca5eda7d404c0518b291412579f55af37d9f1101b"}}
