1. Summary: Pull request introduces new data classes for Fortify vulnerability management, enhances FPR parser with improved XML parsing, and updates corresponding unit tests for better vulnerability scanning validation.

2. Security Findings:

Namespace Handling Improvement:

• XML namespace handling improved to prevent potential XML parsing vulnerabilities
• Uses defusedxml to mitigate XML external entity (XXE) risks

Logging Security Considerations:

• Added logging with logging.getLogger(__name__) for better traceability and potential security monitoring

Input Validation Enhancements:

• More robust parsing of XML elements with explicit namespace handling
• Added type hints and defensive programming techniques
• Improved error handling in severity computation method

Potential Information Exposure Mitigation:

• More structured approach to extracting vulnerability details
• Careful handling of sensitive metadata like source locations

Computational Security:

• Implemented nuanced severity computation method
• Added try/except blocks to handle potential computational errors safely

Vulnerability Findings in Test Data:

• Identified password management issues in HelloWorld.java
• Findings with varying severity levels (Low and High)
