JSR223ScriptExecutor.load() compiles arbitrary script strings via Compilable.compile() and execute() runs them via eval() with no ClassFilter, sandbox, or restricted ScriptContext. The bindings expose `_meta`, `args`, and `extParam`, but Nashorn/JS engines by default give scripts full access to Java reflection (e.g., Java.type('java.lang.Runtime').getRuntime().exec(...)). Comments in Operation.java explicitly warn 'JDK 8~13 可用自带 Nashorn 这个 js 引擎，注意配置 ClassFilter 防脚本注入攻击', but no ClassFilter is configured here. If script content is sourced from a database row, request payload, or any user-influenced channel (which the IF/CODE Operation suggests), this becomes RCE.
