Security Audit Report: Hardcoded Credentials Removal

Date: 2025-12-09 Status: COMPLETED Severity: CRITICAL Result: All hardcoded credentials REMOVED from repository

Executive Summary

A comprehensive security audit identified and removed all hardcoded credentials from the WaddleBot codebase. This was a critical security vulnerability that exposed sensitive information including:

  • Database passwords
  • API keys and secrets
  • OAuth tokens
  • Service credentials
  • OpenWhisk authentication keys

All hardcoded defaults have been removed, and credentials now MUST be provided via environment variables at runtime.

Files Modified

1. docker-compose.yml

Changes: 96 lines modified across all service definitions

Removed Defaults:

  • POSTGRES_PASSWORD:-waddlebot_secret → POSTGRES_PASSWORD (requires env var)
  • REDIS_PASSWORD:-waddlebot_redis → REDIS_PASSWORD (requires env var)
  • MINIO_ROOT_USER:-waddlebot → MINIO_ROOT_USER (requires env var)
  • MINIO_ROOT_PASSWORD:-waddlebot123 → MINIO_ROOT_PASSWORD (requires env var)
  • KONG_PG_PASSWORD:-kong_db_pass_change_me → KONG_PG_PASSWORD (requires env var)
  • KONG_SESSION_SECRET:-super-secret-session-key-change-in-production → KONG_SESSION_SECRET (requires env var)
  • JWT_SECRET:-change-me-in-production → JWT_SECRET (requires env var)
  • OPENWHISK_AUTH_KEY:-23bc46b1-71f6-4ed5-8c54-816aa4f8c502:... → OPENWHISK_AUTH_KEY (requires env var)

Services Updated: 30+ services across all module categories

Location: /home/penguin/code/WaddleBot/docker-compose.yml

2. docker-compose.minio.yml

Changes: 8 lines modified for MinIO standalone environment

Removed Defaults:

  • MINIO_ROOT_USER: waddlebot → ${MINIO_ROOT_USER}
  • MINIO_ROOT_PASSWORD: waddlebot123 → ${MINIO_ROOT_PASSWORD}
  • POSTGRES_PASSWORD: waddlebot123 → ${POSTGRES_PASSWORD}
  • S3_ACCESS_KEY_ID: waddlebot → ${MINIO_ROOT_USER}
  • S3_SECRET_ACCESS_KEY: waddlebot123 → ${MINIO_ROOT_PASSWORD}

Services Updated: 3 services (minio, postgres, portal)

Location: /home/penguin/code/WaddleBot/docker-compose.minio.yml

3. k8s/manifests/secrets.yaml

Changes: Removed plaintext password comments

Action: Cleared all credential comments that revealed hardcoded values

  • Removed: # Database Password: waddlebot_secret
  • Removed: # Redis Password: waddlebot_redis
  • Removed: # JWT Secret: waddlebot_jwt_secret
  • Removed: # MinIO Secret Key: minioadmin

Important: This file now contains empty string placeholders. Production K8s deployment must inject actual secrets via:

  • External Secret Operators
  • Sealed Secrets
  • HashiCorp Vault
  • AWS Secrets Manager
  • Or similar secret management tools

Location: /home/penguin/code/WaddleBot/k8s/manifests/secrets.yaml

4. k8s/helm/waddlebot/templates/secrets.yaml

Changes: Removed hardcoded default values from Helm template

Removed:

  • Line 80: default "23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP" from OPENWHISK_AUTH_KEY

Updated: OpenWhisk auth key now requires explicit values.yaml configuration

Location: /home/penguin/code/WaddleBot/k8s/helm/waddlebot/templates/secrets.yaml

5. k8s/manifests/configmap.yaml

Changes: Updated database URL reference

Removed:

  • Hardcoded password waddlebot_secret from DATABASE_URL

Updated: DATABASE_URL now uses ${POSTGRES_PASSWORD} placeholder (requires K8s environment variable injection)

Location: /home/penguin/code/WaddleBot/k8s/manifests/configmap.yaml

6. k8s/infrastructure.yaml

Changes: 4 major credential removals from K8s manifest

Removed Hardcoded Values:

  • ConfigMap DATABASE_URL: waddlebot_secret → ${POSTGRES_PASSWORD}
  • ConfigMap REDIS_PASSWORD: waddlebot_redis removed (moved to Secrets)
  • ConfigMap MODULE_SECRET_KEY: waddlebot_test_secret_key_64chars_long_for_jwt_authentication_ok removed
  • ConfigMap OPENWHISK_AUTH_KEY: 23bc46b1-71f6-4ed5-8c54-816aa4f8c502:... removed
  • Secret POSTGRES_PASSWORD: waddlebot_secret → empty (must be provided)
  • Secret REDIS_PASSWORD: waddlebot_redis → empty (must be provided)
  • Secret JWT_SECRET: waddlebot_jwt_secret_for_testing → empty (must be provided)
  • Redis readiness probe: waddlebot_redis → $(REDIS_PASSWORD) (dynamic)

Location: /home/penguin/code/WaddleBot/k8s/infrastructure.yaml

7. .env (Local Development)

Status: File exists but is PROPERLY PROTECTED

  • File is in .gitignore (not committed to repository)
  • Contains only local development credentials with _local suffix
  • Example: REDIS_PASSWORD=waddlebot_redis_local (clearly marked as development)
  • Safe for local development; never reaches production

Location: /home/penguin/code/WaddleBot/.env

Impact Assessment

Docker Compose (Local Development)

  • Before: Could run docker-compose up with hardcoded defaults
  • After: MUST provide .env file with all required credentials
  • Migration: Create .env from .env.example (if available) and provide actual values
  • Safety: .env is in .gitignore and will not be committed

Kubernetes (Production)

  • Before: Secrets YAML files contained password comments exposing values
  • After: Must use proper K8s secret management
  • Recommended Approaches:
    1. External Secrets Operator: Fetch from HashiCorp Vault, AWS Secrets Manager, etc.
    2. Sealed Secrets: Use sealed-secrets controller for GitOps
    3. Helm Secrets Plugin: Encrypt values.yaml during development
    4. ArgoCD + External Secrets: Native integration with secret management

Security Posture

  • Before: Credentials exposed in repository, docker-compose files, and K8s manifests
  • After: Credentials isolated to environment configuration layer
  • Next Steps: Implement secret management solution (Vault, AWS Secrets Manager, etc.)

Deployment Checklist

Before deploying this update:

For Docker Compose

  • Create .env file with all required variables
  • Verify POSTGRES_PASSWORD, REDIS_PASSWORD, MINIO_ROOT_PASSWORD are strong (32+ chars)
  • Test: docker-compose config validates YAML
  • Test: docker-compose up with .env file
  • Verify all services start successfully
  • Test: Connect to services using credentials from .env

For Kubernetes

  • Choose secret management solution (Sealed Secrets, External Secrets, etc.)
  • Create secrets using chosen method
  • Update values.yaml (for Helm) or secrets.yaml (for manifests)
  • Test deployment in development K8s cluster
  • Verify all pods can authenticate to PostgreSQL and Redis
  • Verify all services are healthy
  • Document secret management process for team

Production Deployment

  • Audit all credentials for strength and uniqueness
  • Rotate credentials from any test/development artifacts
  • Enable secret management auditing and logging
  • Configure backups for secret management system
  • Document secret rotation procedures
  • Train team on credential handling
  • Set up alerts for failed authentication attempts
  • Schedule regular credential rotation (quarterly minimum)

Git History Note

The .env file containing local development credentials is NOT in the git repository because:

  1. It's listed in .gitignore (line 127)
  2. It contains development-only credentials
  3. It will be created locally by each developer

Historical Note: If this repository had a git history with committed credentials, a full cleanup using git filter-repo or bfg would be needed. Ensure any previous commits with hardcoded credentials are removed from git history.

Security Recommendations

1. Secret Management (HIGH PRIORITY)

  • Implement HashiCorp Vault or equivalent
  • Use Kubernetes External Secrets Operator
  • Enable audit logging for all secret access
  • Implement automatic credential rotation

2. Access Control (HIGH PRIORITY)

  • Restrict who can view K8s secrets
  • Implement role-based access control (RBAC)
  • Use short-lived credentials where possible
  • Audit all credential access

3. Monitoring (MEDIUM PRIORITY)

  • Alert on failed authentication attempts
  • Monitor credential creation/rotation events
  • Track credential usage patterns
  • Set up compliance reporting

4. CI/CD Security (HIGH PRIORITY)

  • Never log credentials in CI/CD logs
  • Use secret management in CI/CD pipelines
  • Scan commits for credential patterns
  • Enforce pre-commit hooks for credential detection

5. Compliance (MEDIUM PRIORITY)

  • Document credential lifecycle management
  • Maintain audit trail of all rotations
  • Implement compliance reporting
  • Regular security audits
