Mitigation checklist
- To mitigate this issue, users should ensure that only trusted Java Archive (JAR) files are processed by the `nltk` Stanford interface classes. Avoid loading JAR files from untrusted sources, as this vulnerability allows for arbitrary code execution. Implement strict input validation and source verification for any JAR files used with `nltk` to prevent the execution of malicious code.
