Is this vulnerability remotely exploitable over the internet?

It is exploitable through the Sonicverse dashboard interface by anyone who has authenticated operator access. The attacker does not need direct network access to internal services; instead, they abuse the dashboard backend as a proxy to reach those services.

What level of access does an attacker need to exploit this issue?

The issue requires authenticated access to the Sonicverse dashboard with the ability to interact with features that accept URLs. No direct system shell or container-level access is needed, but the operator role must be able to supply or influence URLs processed by the backend.

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

The most robust fix is to eliminate or tightly constrain user-driven outbound requests: replace arbitrary URL fetching with a curated set of allowed endpoints, enforce strict validation and network restrictions, and ensure the backend cannot contact private or sensitive network ranges based solely on user input.
