{"schema":"threatline.record/2","record":{"id":"CVE-2026-96400","aliases":["GHSA-54w9-6cc5-9wj9"],"summary":"Gitea migration SSRF to reserved addresses through ALLOWED_DOMAINS","details":"With `[migrations] ALLOWED_DOMAINS` set to a matching entry such as `*` or a hostname wildcard, Gitea's migration URL validation could permit reserved and link-local addresses, such as `169.254.169.254`, even when `ALLOW_LOCALNETWORKS = false`. The local-network block list did not cover these ranges, and a hostname matching the allow list was accepted regardless of its resolved address. A user who can start migrations on such an instance could reach these addresses from the Gitea server; the default empty `ALLOWED_DOMAINS` configuration is not affected.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96400","source_modified_at":"2026-10-07T11:35:27.280Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Gitea","vendor":"Gitea","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.27.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00199,"percentile":0.09258,"score_date":"2026-10-23"},"published_at":"2026-10-06T19:25:23.261Z","modified_at":"2026-10-07T11:35:27.280Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-96400","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T11:35:27.280Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-96400","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-54w9-6cc5-9wj9","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39426","tags":["patch"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-28.0.0/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v28.0.0","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":"2026-10-07T11:35:23.694637Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T11:35:27.280Z","content_hash":"44da60d572223c8985db71362f748424d6e28292e216d9c7bfb858babd634f0a"}}
