CRITICAL SECURITY FIXES

Overview

This document tracks critical security vulnerabilities found and fixed in agentic-brain V4.

Fixed Vulnerabilities

1. ⚠️ CRITICAL: Removed Unnecessary Pickle Import

  • File: src/agentic_brain/enterprise/disaster_recovery.py
  • Issue: Imported pickle module but never used it
  • Risk: Creates unnecessary attack surface
  • Fix: Removed unused pickle import
  • CWE: CWE-502 (Deserialization of Untrusted Data)

2. ⚠️ HIGH: Hardcoded Default Webhook Secret

  • File: src/agentic_brain/commerce/chatbot/chatbot/wp_hooks.py
  • Issue: Default webhook secret was "change-me"
  • Risk: Predictable secrets enable webhook tampering
  • Fix: Changed default to empty string with security comment
  • CWE: CWE-798 (Use of Hard-coded Credentials)

3. ⚠️ HIGH: Enhanced Demo Credentials Security

  • File: src/agentic_brain/auth/demo/simple_auth.py
  • Issue: Hardcoded admin/admin credentials in demo mode
  • Risk: Default credentials in production deployments
  • Fix:
    • Made demo passwords configurable via environment variables
    • Added clear security warnings in UI
    • Masked passwords in help text
  • CWE: CWE-798 (Use of Hard-coded Credentials)

4. ⚠️ MEDIUM: Subprocess Security Hardening

  • File: src/agentic_brain/benchmark/runner.py
  • Issue: subprocess calls without proper error handling
  • Risk: Potential command injection or information disclosure
  • Fix: Added check=False parameter to prevent exceptions on errors
  • CWE: CWE-78 (OS Command Injection)

Security Recommendations

For Development

  1. Set secure demo passwords:

    export DEMO_ADMIN_PASSWORD="secure_random_password"

  2. Configure webhook secrets:

    export WEBHOOK_SECRET="your_secure_webhook_secret"

For Production

  1. Never use demo authentication - implement proper auth provider
  2. Set all secrets via environment variables - never hardcode
  3. Review all subprocess calls - validate inputs
  4. Regular security audits - use tools like bandit, semgrep

Verification Commands

Run these commands to verify the fixes:

# 1. Verify no pickle usage in disaster recovery
grep -n "pickle" src/agentic_brain/enterprise/disaster_recovery.py
# Should return no matches

# 2. Verify webhook secret is not hardcoded
grep -n "change-me" src/agentic_brain/commerce/chatbot/chatbot/wp_hooks.py
# Should return no matches

# 3. Verify demo passwords are configurable
grep -n "DEMO_ADMIN_PASSWORD" src/agentic_brain/auth/demo/simple_auth.py
# Should find environment variable usage

# 4. Check for additional hardcoded secrets
grep -rn "password.*=" src/agentic_brain/ --include="*.py" | grep -v "None\|environ\|getenv"

Next Steps

  1. Implement proper secret management (HashiCorp Vault, AWS Secrets Manager)
  2. Add security linting to CI/CD pipeline (bandit, semgrep)
  3. Regular penetration testing
  4. Implement security headers for web endpoints
  5. Add rate limiting and DDoS protection
