Is this vulnerability remotely exploitable over the internet?

Yes. If the `salvo-proxy`-based service is exposed to the internet, an unauthenticated remote client can attempt to exploit the issue simply by crafting malicious request paths.

Does an attacker need valid credentials to exploit this bug?

No. The weakness occurs in the proxy's path handling prior to any application-specific authentication, so exploitation can be attempted without logging in, assuming the affected routes are publicly reachable.

What is the safest general fix pattern for developers?

Adopt strict path normalization and validation before forwarding requests: canonicalize paths, reject traversal attempts, and ensure that allowed upstream paths are defined via explicit allowlists rather than relying on generic encoding functions.
