CVE-2026-96400Network attack vectorHinoki check available

Authenticated SSRF via migration hostname allow-list bypass

Published Oct 6, 2026 · Updated Oct 6, 2026

Server-side request forgery in Gitea 1.27.3 and earlier allows remote authenticated users to reach reserved addresses through repository migration. The migration URL check accepts a hostname matching ALLOWED_DOMAINS even when its resolved address fails the IP allow check, while the local-network block list does not cover every reserved range. Exploitation requires permission to start migrations and a matching nonempty allow list; the default empty ALLOWED_DOMAINS setting is not affected.
