Description
SurrealDB versions 3.2.0 up to but not including 3.3.0 contain a server-side request forgery (SSRF) vulnerability. The issue arises from the FilteringResolver's is_private_ip check, which fails to properly unwrap certain IPv6 transition addresses (NAT64, 6to4, Teredo). Authenticated users can exploit this by triggering outbound HTTP requests via SurrealQL HTTP functions, potentially reaching internal services, localhost, or cloud metadata endpoints. The vulnerability has a medium severity with a CVSS score of 4.8. A fix is available in SurrealDB version 3.3.0.
