Summary

SurrealDB from 3.1.0 before 3.3.0 contains a server-side request forgery flaw (CWE-918) in its JWKS URL handling. A database Owner can bypass port-specific deny-net rules by using JWKS URLs with implicit default ports 80 or 443, so blind GET requests reach explicitly denied internal services. The Owner does this by configuring a JWT or record access method whose JWKS URL omits the port.
