Is this vulnerability remotely exploitable?

Yes. If the logos search endpoint is reachable over the network (for example, over the internet or from untrusted clients), an attacker can remotely trigger SSRF by sending crafted requests, provided they can influence or leverage the proxy configuration and search terms.

Does an attacker need authenticated access to exploit this issue?

It depends on how Wallos is deployed. If the logos search functionality is available to unauthenticated users, no login is required; otherwise, any account that can access this endpoint may be sufficient. The key requirement is the ability to reach `endpoints/logos/search.php` and interact with its parameters.

What is the safest general fix pattern for this kind of bug?

The most robust pattern is to decouple user input from raw network destinations, enforce strict allowlists for any server-initiated HTTP calls, and avoid inheriting global proxy configuration for request paths influenced by users. Application code should explicitly control its HTTP client configuration rather than trusting ambient environment variables.
