SurrealDB: Port-specific --deny-net rules silently bypassed on HTTP redirect
GitHub lists this reviewed advisory for surrealdb. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.

source listed< 3.1.0
SurrealDB offers `http::*` functions that can access external network endpoints, with the `--allow-net` and `--deny-net` capabilities used to restrict the set of network targets that can be reached. An authenticated user of SurrealDB can bypass a port-scoped `--deny-net :` rule by chaining an HTTP redirect: the initial request goes to an `--allow-net`-permitted hostname, the response's `3xx Location` header points at the denied `host:port`, and the redirect is followed even though the destination was explicitly denied. The root cause is in the redirect policy applied to outbound HTTP requests (`surrealdb/core/src/fnc/util/http/mod.rs`): the `NetTarget` for the redirect destination is built from `url.host_str()` alone and `url.port()` is dropped. The capability matcher (`surrealdb/core/src/dbs/capabilities.rs:259-264`) refuses to match a port-bearing rule against a port-stripped target (`Self::Host(host, Some(port)) => match tgt { _ => false }`), so the operator's port-scoped deny rule silently does not fire on the redirect target. ### Impact The impact of this vulnerability is circumvention of the `--deny-net` capability when the operator has scoped deny rules by por

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
