Is this vulnerability remotely exploitable?

Yes, it can be exploited remotely, but only by an attacker who can authenticate to the OpenPLC v3 interface and has sufficient permissions to upload or modify hardware configurations.

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

The attacker must possess valid credentials with rights to manage hardware configuration layers. Without authenticated access, the vulnerable functionality is not directly reachable.

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

The most robust pattern is to eliminate direct execution of user-supplied code in configuration paths. Where extensibility is required, constrain it to a well-defined, declarative format or a heavily sandboxed extension model with strict validation of allowed operations.
