Is this vulnerability remotely exploitable over the internet?

It can be abused remotely wherever the pyLoad API is reachable and an attacker can obtain or compromise an account with ADD permission. The SSRF then lets them reach resources that are only visible from the pyLoad server's network context.

What level of access does an attacker need?

The attacker needs authenticated access with ADD permission to invoke the parse_urls API. Anonymous users generally cannot trigger the vulnerable behavior unless permissions are misconfigured.

What is the safest general fix pattern?

The safest pattern is to introduce a hardened URL fetching layer that: - Accepts only well-formed HTTP(S) URLs - Enforces host/IP allowlists or robust blocklists for internal and metadata addresses - Disables non-essential protocols like file://, gopher://, and dict:// - Is used consistently wherever URLs are fetched on behalf of users.
