Is this vulnerability remotely exploitable over the internet?

Yes, if the Gokapi instance is accessible over the network and an attacker can obtain an authenticated account, they can upload a malicious SVG and share the hotlink with other users, including over the internet.

Does exploitation require authentication or special privileges?

Exploitation requires an authenticated user account with permission to upload files and generate hotlinks. No special administrative privileges are necessary beyond that capability.

What is the safest general fix pattern for this issue?

The safest general fix is to either disallow SVG uploads entirely or handle SVG uploads with strict sanitization and isolation. Serving user-uploaded content from a separate, unprivileged origin and enforcing a strong Content Security Policy significantly reduces risk.
