Is this vulnerability remotely exploitable?

Yes. The issue resides in a network-accessible Administrative API endpoint, so an attacker can exploit it remotely if they can reach the `/api` interface.

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

The attacker generally only needs network-level reachability to the API. Because it is an authorization bypass, valid administrative credentials are not required if the vulnerable code path is accessible.

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

The most robust fix is to centralize and enforce strict authorization checks on all administrative endpoints. Each admin operation should require authenticated sessions and explicit permission validation, mediated through a shared access control layer.
