🔒 Security Impact

• Before: Vulnerable to DoS attacks via malicious YAML input
• After: Protected against stack overflow attacks in YAML parsing
• Risk Reduction: Eliminates known DoS vulnerability

🧪 Testing Recommendations

• Test YAML parsing with complex nested structures
• Verify application handles malformed YAML gracefully
• Run security scans to validate fix
• Test all functionality that involves YAML parsing
• Verify no regression in existing YAML processing features

📝 Additional Notes

This update addresses a known vulnerability in SnakeYAML that could allow attackers to cause denial of service through stack overflow exceptions. The fix is implemented by upgrading to version 1.31, which includes proper input validation and stack depth checking.
