Is this vulnerability remotely exploitable over the internet?

It can be triggered remotely, but only by authenticated users who have the necessary permissions on upload-enabled collections. Unauthenticated users cannot directly exploit it in typical configurations.

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

The attacker must have a valid account with create or update rights for at least one collection that supports uploads. They do not need administrative access, but their role must allow them to trigger the upload workflow.

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

Centralize all outbound HTTP calls behind a strict validation layer that enforces allowlisted hosts and schemes, and couple this with network-level egress restrictions. Avoid building URLs directly from user input, and ensure any necessary user-influenced URLs are rigorously validated against a narrow set of permitted destinations.
