Solutions

1. Filter and escape user input to ensure that it does not contain malicious Java code. 2. Use safe apis and functions to execute code. Avoid directly concatenating user input into code. 3. Conduct regular security audits and tests to find potential code injection vulnerabilities and fix them in time.
