+# Security Audit Report
+
+**Date:** 2026-02-06  
+**Status:** Completed Initial Assessment
+
+## Executive Summary
+
+This document tracks security vulnerabilities found in DocuElevate and their remediation status.
+
+## Critical Vulnerabilities (Fixed) ✅
+
+### 1. Outdated Authlib with Known Vulnerabilities
+**Status:** ✅ FIXED  
+**Severity:** HIGH  
+**Description:** Authlib version 1.3.2 had two critical vulnerabilities:
+- CVE: Denial of Service via Oversized JOSE Segments
+- CVE: JWS/JWT accepts unknown crit headers (RFC violation → possible authz bypass)
+
+**Fix:** Updated `requirements.txt` to require `authlib>=1.6.5`
+
+### 2. Starlette DoS Vulnerability
+**Status:** ✅ FIXED  
+**Severity:** MEDIUM  
+**Description:** Starlette 0.41.3 vulnerable to O(n^2) DoS via Range header merging in `FileResponse`
+
+**Fix:** Updated `requirements.txt` to require `starlette>=0.49.1`
+
+### 3. Weak SESSION_SECRET Default
+**Status:** ✅ FIXED  
+**Severity:** HIGH  
+**Description:** Default SESSION_SECRET value in `app/main.py` was a predictable string that could be exploited if not overridden
+
+**Fix:** 
+- Enhanced validation in `app/main.py` to raise error if auth is enabled without proper secret
+- Updated default to be clearly marked as insecure for development only
+- Added generation instructions in error message
+
+## Medium Risk Issues (Fixed) ✅
+
+### 4. Insufficient .gitignore Protection
+**Status:** ✅ FIXED  
+**Severity:** MEDIUM  
+**Description:** .gitignore didn't adequately protect against accidentally committing sensitive files (credentials, private keys, secrets)
+
+**Fix:** Enhanced `.gitignore` with comprehensive patterns for:
+- Various environment file formats
+- Credential JSON files
+- Private keys (.pem, .key, .pfx, etc.)
+- SSH keys
+- Explicit exclusion of patterns where needed
+
+## Best Practices Implemented
+
+### Dependency Management
+- ✅ Version pinning for security-critical packages (authlib, starlette)
+- ✅ Advisory database checks integrated into development workflow
+- ⏳ TODO: Add automated dependency vulnerability scanning in CI/CD
+
+### Authentication & Secrets
+- ✅ Strong validation for SESSION_SECRET (minimum 32 characters)
+- ✅ Error-on-missing for critical security settings when auth enabled
+- ✅ Clear documentation of secret generation methods
+- ✅ .env.demo file for configuration examples (no real secrets)
+
+### Configuration Security
+- ✅ All secrets loaded from environment variables
+- ✅ No hardcoded credentials in codebase
+- ✅ Proper masking in configuration validators
+
+## Ongoing Security Measures
+
+### CI/CD Security
+- ⏳ **TODO:** Add CodeQL scanning to GitHub Actions
+- ⏳ **TODO:** Add Bandit (Python security linter) to CI pipeline
+- ⏳ **TODO:** Add dependency vulnerability scanning (Safety, pip-audit)
+- ⏳ **TODO:** Make security scans blocking (fail on critical issues)
+
+### Code Security
+- ⏳ **TODO:** Implement rate limiting on API endpoints
+- ⏳ **TODO:** Add CSRF protection for state-changing operations
+- ⏳ **TODO:** Implement request size limits
+- ⏳ **TODO:** Add input sanitization for all user inputs
+- ⏳ **TODO:** Implement proper API key rotation mechanisms
+
+### Infrastructure Security
+- ✅ TrustedHostMiddleware configured
+- ✅ ProxyHeadersMiddleware for reverse proxy setup
+- ⏳ **TODO:** Add security headers (HSTS, CSP, X-Frame-Options)
+- ⏳ **TODO:** Implement proper CORS configuration
+- ⏳ **TODO:** Add request logging with sensitive data masking
+
+## Recommendations
+
+### High Priority
+1. **Enable CodeQL scanning** - Automated security vulnerability detection
+2. **Implement rate limiting** - Prevent abuse and DoS attacks
+3. **Add comprehensive input validation** - Prevent injection attacks
+4. **Implement API authentication** - Secure all API endpoints properly
+
+### Medium Priority
+1. **Add security headers** - Improve browser-side security
+2. **Implement audit logging** - Track security-relevant events
+3. **Add automated security testing** - Integration with CI/CD
+4. **Document security architecture** - Security design decisions
+
+### Low Priority
+1. **Security training documentation** - For contributors
+2. **Penetration testing** - Professional security assessment
+3. **Bug bounty program** - Community security contributions
