Hardcoded credentials present a serious security vulnerability. The username 'admin' and password 'password123' should be replaced with a secure authentication mechanism using hashed passwords stored in a database or secure configuration file.

[nitpick] Magic number 4096 should be defined as a constant for better maintainability. Consider defining a constant like MAX_RESULT_SIZE to make the buffer size configurable.

The CGI directory allows unrestricted access with 'Require all granted'. This should be restricted to authenticated users or specific IP ranges to prevent unauthorized execution of CGI scripts.

The Content Security Policy is too restrictive and may break functionality. Consider adding necessary sources for scripts, styles, and other resources. For example: 'default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline''.

Using sudo in a script that processes user-supplied file paths creates a potential privilege escalation vulnerability. The script should run with appropriate permissions without requiring sudo, or implement proper input sanitization and path validation.

[nitpick] The magic number 1024 for path buffers is used multiple times. Define a constant like MAX_PATH_SIZE to ensure consistency and make it easier to adjust if needed.
