# Security Audit Report - August 28, 2025

## Executive Summary

Security audit performed for PMAT v2.17.0 using `cargo audit v0.21.2`.

**Result**: ✅ **LOW RISK** - No critical vulnerabilities found

## Findings

### Warnings (1 total)

#### RUSTSEC-2024-0436: paste crate unmaintained
- **Crate**: paste v1.0.15
- **Severity**: Warning (unmaintained)
- **Risk Level**: Low
- **Description**: The `paste` crate is no longer maintained as of 2024-10-07
- **Dependencies**: 
  - ratatui → pmat
  - malachite-bigint → rustpython-parser → pmat

#### Impact Assessment
- **Functional Impact**: None - `paste` is a procedural macro crate
- **Security Impact**: Low - unmaintained but stable functionality
- **Upgrade Path**: Consider alternatives if maintenance becomes critical

## Recommendations

### Immediate Actions (v2.17.x)
- ✅ **No immediate action required** - no critical vulnerabilities
- 📝 Monitor `paste` crate for security advisories

### Sprint 2 Priorities (v2.18.0)
1. **Dependency Coordination** (Issue #18)
   - Update SWC ecosystem dependencies together
   - Coordinate gimli, goblin, tree-sitter updates
   - Test language parser functionality

2. **Maintenance Updates**
   - Review unmaintained dependencies periodically
   - Consider `paste` alternatives if needed
   - Update minor version dependencies

3. **Preventive Measures**
   - Add dependency group configuration for Dependabot
   - Implement automated security scanning in CI/CD

## Historical Context

The open security issues (#10, #17, #22, #25) appear to be GitHub Actions workflow-generated alerts for dependency updates, not actual critical vulnerabilities. Current audit confirms the project has good security posture.

## Next Review

Scheduled for v2.18.0 release or 90 days from this audit date.
