Module path_validator 

Cross-Platform Path Validation Module

This module provides robust, platform-agnostic path validation that prevents:

• Directory traversal attacks (../, .., encoded variants)
• Absolute path access (/etc/passwd, C:\Windows\System32)
• UNC path attacks (\server\share)
• URL-encoded traversal (%2e%2e/, %252e%252e/)
• Null byte injection (file.xml%00.txt)
• Symlink attacks and canonicalization issues
• Unicode normalization attacks

The validator works identically across Windows, Linux, and macOS by:

• Normalizing all paths to forward slashes internally
• Using platform-specific canonicalization when available
• Implementing whitelist-based validation
• Resolving symlinks and checking final destinations
