Is this vulnerability remotely exploitable over the internet?

Yes, if the administrative interface is accessible over the network and an attacker can authenticate as an administrator or compromise an admin account, the vulnerability can be exploited remotely.

Does exploitation require administrative privileges?

The described issue requires access to plugin configuration parameters, which are typically restricted to authenticated administrators. An attacker would need valid admin credentials or a way to hijack an existing admin session.

What is the safest general fix pattern for this vulnerability class?

The safest pattern is to completely remove any dynamic evaluation of configuration values and ensure that configuration is always treated as non-executable data, backed by strict validation and whitelisting of acceptable values.
