Closes #332

Security Fix Summary

  • Vulnerability: YAML Deserialization Remote Code Execution
  • Severity: Critical (CVSS 9.8)
  • Fix: Use yaml.safe_load() instead of yaml.load()

Technical Details

This fix addresses the YAML deserialization vulnerability by:

  1. Using yaml.safe_load() to prevent code execution
  2. Implementing input validation for YAML data
  3. Adding secure error handling

Testing

  • YAML RCE payloads tested and blocked
  • Command execution prevented
  • Normal YAML processing still works
  • No regression in functionality

References
