CVE-2026-82556Public exploitNetwork attack vectorHinoki check available

Server-side request forgery via migration hostname lookup

Published Aug 30, 2026 · Updated Aug 30, 2026

SSRF in Forgejo 15.0.0 through 15.0.4 allows remote attackers to make server-originated requests via repository migration. The allowlist check in services/migrations/allowlist/is_migrate_allowed.go passes an attacker-controlled migration host to net.LookupIP without sufficiently ensuring that the resolved destination is expected. Exploitation lets the server contact arbitrary internal or external resources; public records do not state whether authentication is required.
