# Security Tasklist - Kilo Codebase

## Comprehensive Security Assessment

Based on a thorough analysis of the Kilo codebase, this document outlines the security posture, identifies vulnerabilities, and provides a prioritized tasklist for security improvements.

---

## 1. Security Architecture Overview

The codebase has a well-structured security module with multiple layers of protection:
- **Authentication**: JWT tokens, API keys, session management
- **Authorization**: RBAC (Role-Based Access Control) system
- **Input Validation**: SQL injection prevention, XSS protection, path traversal detection
- **Security Headers**: CSP, HSTS, XSS protection headers
- **Rate Limiting**: Governor-based rate limiting for API endpoints
- **Error Handling**: Error sanitization to prevent sensitive data exposure
- **Command Execution**: SafeCommand wrapper for command injection prevention
- **Audit Logging**: Comprehensive audit event tracking
- **Encryption**: Data encryption, TLS, mTLS support
- **Secrets Management**: Vault integration

---

## 2. Current Security Posture

### Strengths:
1. **Comprehensive security module** with 60+ security-related files
2. **Multiple authentication methods** (JWT, API keys, sessions)
3. **RBAC system** with fine-grained permissions
4. **SQL injection prevention** via SQL guard
5. **Command injection prevention** via SafeCommand
6. **XSS protection** via security headers and input sanitization
7. **Rate limiting** for API endpoints
8. **Error sanitization** to prevent sensitive data exposure
9. **Audit logging** for security events
10. **TLS/mTLS support** with certificate management

### Weaknesses:
1. **Default CSP includes unsafe-inline and unsafe-eval**
2. **Passkey implementation is incomplete** (commented out)
3. **Some files still use Command::new directly** instead of SafeCommand
4. **Potential for path traversal vulnerabilities** in file operations
5. **JWT secret management** uses default secret if not configured
6. **CORS configuration** has permissive default origins in development
7. **Some endpoints have excessive anonymous access**
8. **Error handling could be more robust** in some areas
