LLM plugins are extensions that, when enabled, are called automatically by the model during user interactions. They are driven by the model, and there is no application control over the execution. Furthermore, to deal with context-size limitations, plugins are likely to implement free-text inputs from the model with no validation or type checking. This allows a potential attacker to construct a malicious request to the plugin, which could result in a wide range of undesired behaviors, up to and including remote code execution.
