Is this vulnerability remotely exploitable over the internet?

Yes, if the affected API endpoints are exposed to the internet or any untrusted network, an attacker can remotely exploit the issue without authentication by sending crafted requests with chosen identifiers.

Does exploiting this vulnerability require valid user credentials or an existing session?

No. The core problem is that the endpoints do not require authentication or enforce authorization, so no valid session, token, or user account is needed to access the exposed data.

What is the safest general fix pattern for this issue?

The most robust fix is to enforce authentication and authorization on all sensitive API endpoints, centralize access control through shared middleware or policies, and validate that every requested record belongs to or is permitted for the authenticated caller before returning any data.
