Is this vulnerability remotely exploitable?

Yes, the flaw resides in a remotely accessible OpenAPI endpoint. If the endpoint is exposed to untrusted clients and they can control `nodeParams`, they may be able to trigger code execution.

Does an attacker need authenticated access to exploit this issue?

That depends on the deployment. If `/openApi/addWorkflowNode` requires authentication or specific roles, an attacker would first need those credentials or to compromise a user with access. However, if the endpoint is misconfigured as publicly accessible, anonymous exploitation becomes more feasible.

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

The most robust fix is to eliminate dynamic evaluation of client-provided input entirely. Replace `GroovyEvaluator.evaluate` on untrusted data with deterministic, parameterized logic or a constrained configuration format where all operations are predefined and data-driven rather than code-driven.
