{"id":"BIT-gitea-2026-70357","summary":"Gitea repository migration SSRF through DNS rebinding","details":"Gitea validates a repository migration hostname against its network allow and block lists before invoking Git, but the Git subprocess independently resolves the hostname when connecting. An attacker who can start a migration and control the destination's DNS can change the address between validation and connection to reach a blocked internal address. The affected path is the Git clone operation; validation in the migration HTTP client's dialer does not protect the independently connecting Git subprocess.","aliases":["CVE-2026-70357","GHSA-p3pc-g8m5-hrrr"],"modified":"2026-10-14T11:11:10.443423990Z","published":"2026-10-14T08:42:59.802Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:gitea:gitea:*:*:*:*:*:*:*:*"]},"references":[{"type":"ARTICLE","url":"https://blog.gitea.com/release-of-28.0.0/"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39426"},{"type":"ARTICLE","url":"https://github.com/go-gitea/gitea/releases/tag/v28.0.0"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-p3pc-g8m5-hrrr"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70357"}],"affected":[{"package":{"name":"gitea","ecosystem":"Bitnami","purl":"pkg:bitnami/gitea"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"28.0.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/gitea/BIT-gitea-2026-70357.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.9.0"}
