Is this vulnerability remotely exploitable over the internet?

Yes. The vulnerable endpoint is reachable without authentication, so a remote attacker can exploit it by sending crafted HTTP requests that control the URL the server accesses.

Does an attacker need valid credentials or admin access to exploit this issue?

No. The description indicates that exploitation does not require authentication; any remote client that can reach /admin/read.php can attempt to trigger SSRF behavior.

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

The most robust pattern is to avoid issuing server-side requests to arbitrary user-supplied URLs. Where such behavior is required, enforce a strict allowlist of destinations, validate schemes and IP ranges, and back these controls with network-level egress restrictions.
