================================================================================

This security audit provides a comprehensive analysis of the RAG Document QA
system's security posture, identifies 73 vulnerabilities across multiple
severity levels, and provides detailed remediation guidance with ready-to-use
code examples and testing procedures.

The audit materials total over 4,100 lines of documentation across 4 documents,
providing complete guidance from executive summary through detailed code-level
implementation.

Timeline for remediation: 10 hours (P0) + 12 hours (P1) = 22 hours of work
for critical fixes, with additional medium and low priority items scheduled
over the next 6 months.

All recommendations are actionable, include effort estimates, provide code
examples, and include testing procedures for verification.
