Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

SurrealDB versions before 3.1.0 (crates.io package surrealdb) fail to apply port-specific --deny-net rules to HTTP redirect targets. An authenticated user permitted to call http::* functions can point a redirect from an allowed host at a denied host and port, and the request is followed anyway. Upgrade to surrealdb 3.1.0 or later. If upgrading is not possible, replace port-specific deny rules with host-only deny rules or disable http::* for untrusted users.
