Is this vulnerability remotely exploitable?

The description indicates a local attacker requirement, so exploitation generally requires local access to the host or environment where fastCMS runs. Remote exploitation would only be possible if local-only interfaces or plugin inputs are indirectly exposed over the network by other weaknesses.

What level of access does an attacker need?

An attacker typically needs local access sufficient to influence data consumed by `PluginController`—for example, the ability to create or modify plugin files, metadata, or configuration on the host or inside the container where fastCMS is deployed.

What is the safest general fix pattern?

The safest pattern is to eliminate or strictly limit dynamic code execution based on plugin-supplied data: confine plugin loading to trusted, validated artifacts, enforce strict input validation, and use controlled class loading or sandbox mechanisms that cannot execute arbitrary attacker-controlled code.
