Test 3

Summary by Bito

This pull request introduces new modules in Python, Java, and Go that extend user management, command execution, file operations, and debugging capabilities. It addresses several critical security vulnerabilities by replacing insecure MD5-based password hashing with bcrypt, implementing SecureRandom and custom validating deserialization, and enhancing error handling for file upload operations. The code previously contained SQL injection, command injection, path traversal, and insecure deserialization issues that required immediate remediation.
