Is this vulnerability remotely exploitable?

Yes. An attacker with network access to the Smanga instance can exploit this issue remotely without prior authentication, by crafting malicious POST requests.

Does this require valid credentials or an existing account?

No. The weakness lies in missing or ineffective authentication and authorization checks in `check-power.php`, allowing unauthenticated users to trigger password resets for arbitrary accounts.

What is the safest general fix pattern for this issue?

The most robust fix is to enforce that all sensitive operations, including password resets and account changes, derive the acting user identity from authenticated session data and perform explicit role/ownership checks before executing any action.
