Is this vulnerability remotely exploitable over the network?

Yes. Any remote user who can send HTTP requests to the Webgrind instance can attempt to exploit the vulnerability, as it affects a publicly reachable parameter in index.php.

Does an attacker need authentication or special privileges to exploit this issue?

No. The described behavior is unauthenticated; attackers do not need valid credentials or prior access, only network reachability to the Webgrind interface.

What is the safest general fix pattern for this flaw?

The safest approach is to remove direct shell command construction from user input entirely, replacing it with safe, high-level APIs that operate on validated, whitelisted file identifiers rather than arbitrary strings, and avoiding shell invocation where possible.
