# 🚨 CRITICAL SECURITY REMEDIATION REQUIRED

**Status:** ⛔ **DO NOT PUSH TO GITHUB YET**  
**Date:** 2025-11-11  
**Severity:** CRITICAL

## Security Issue Discovered

After importing source code from le-chantier, security scanning revealed **hardcoded API keys in 40+ files** scattered throughout the codebase.

## API Keys Found

**Two API keys hardcoded in multiple locations:**

1. **Colossus API Key:** `sk-dBoxml3krytIRLdjr35Lnw`
2. **OpenRouter API Key:** `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`

## Affected Files (40+ instances)

### Agents (6 instances)
- `backend/agents/colossus_agent.py` - Default api_key parameter
- `backend/agents/colossus_saap_agent.py` - API_KEY constant
- `backend/agents/openrouter_agent_enhanced.py` - API_KEY constant
- `backend/agents/openrouter_saap_agent.py` - COLOSSUS_KEY constant

### API Clients (2 instances)
- `backend/api/colossus_client.py` - Default api_key parameter
- `backend/api/openrouter_client.py` - Hardcoded api_key variable

### Configuration (4 instances)
- `backend/config/settings.py` - Default values for both keys (2 instances)
- `backend/settings.py` - Duplicate default values (2 instances)

### Models & Schemas (12+ instances)
- `backend/models/agent.py` - Template defaults (3 instances)
- `backend/models/agent_schema.json` - Schema examples (3 instances)
- `backend/models/agent_templates.json` - Template defaults (5 instances)
- `backend/agent.py` - Duplicate file (3 instances)
- `backend/agent_schema.json` - Duplicate schema (3 instances)
- `backend/agent_templates.json` - Duplicate templates (5 instances)

### Services (3 instances)
- `backend/services/agent_manager_hybrid.py` - Default fallback
- `backend/services/agent_manager_hybrid_fixed.py` - Default fallback
- `backend/services/openrouter_integration.py` - Constructor default
- `backend/openrouter_integration.py` - Duplicate file
- `backend/agent_manager_hybrid.py` - Duplicate file
- `backend/agent_manager_hybrid.py.backup` - Backup file
- `backend/agent_manager_hybrid_fixed.py` - Duplicate file

### Scripts & Tests (1 instance)
- `backend/scripts/test_colossus_integration.py` - Test API_KEY constant
- `backend/test_colossus_integration.py` - Duplicate file

### Main Application (1 instance)
- `backend/main.py` - Hardcoded openrouter_key variable

### Environment Template (2 instances)
- `backend/.env.example` - **BOTH keys present** (may be acceptable for examples, but verify these are dummy keys first)

## Remediation Plan

### Option 1: Environment Variables (Recommended)

**Replace all hardcoded keys with environment variable lookups:**

```python
# BEFORE (agents/colossus_agent.py)
api_key: str = "sk-dBoxml3krytIRLdjr35Lnw"

# AFTER
import os
api_key: str = os.getenv("COLOSSUS_API_KEY", "")
```

```python
# BEFORE (config/settings.py)
default="sk-dBoxml3krytIRLdjr35Lnw"

# AFTER
default=os.getenv("COLOSSUS_API_KEY", "")
```

### Option 2: Remove Defaults Entirely (Most Secure)

**Force explicit configuration, no fallbacks:**

```python
# BEFORE
api_key: str = "sk-dBoxml3krytIRLdjr35Lnw"

# AFTER
api_key: str  # No default - must be provided explicitly
```

### Option 3: Use Placeholder Values

**Replace with obvious placeholders:**

```python
# BEFORE
api_key: str = "sk-dBoxml3krytIRLdjr35Lnw"

# AFTER
api_key: str = "YOUR_COLOSSUS_API_KEY_HERE"
```

## Automated Remediation Script

```bash
#!/bin/bash
# cleanup-secrets.sh

# Replace Colossus API key with environment variable
find backend/ -type f -name "*.py" -exec sed -i \
  's/sk-dBoxml3krytIRLdjr35Lnw/os.getenv("COLOSSUS_API_KEY", "")/g' {} +

# Replace OpenRouter API key with environment variable
find backend/ -type f -name "*.py" -exec sed -i \
  's/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/os.getenv("OPENROUTER_API_KEY", "")/g' {} +

# For JSON files - replace with placeholders
find backend/ -type f -name "*.json" -exec sed -i \
  's/sk-dBoxml3krytIRLdjr35Lnw/YOUR_COLOSSUS_API_KEY_HERE/g' {} +

find backend/ -type f -name "*.json" -exec sed -i \
  's/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/YOUR_OPENROUTER_API_KEY_HERE/g' {} +

echo "✅ Secrets remediated - verify changes before committing"
```

## Manual Review Required

**Before running automated fixes:**

1. **Verify if these are real API keys or test keys**
   - If test keys: Can replace with placeholders
   - If real keys: **MUST invalidate/rotate immediately**

2. **Check .env.example**
   - If these are example keys: Acceptable to keep
   - If real keys: Replace with `YOUR_*_API_KEY_HERE`

3. **Add `import os` statements**
   - Python files using `os.getenv()` need `import os` at top

## Immediate Actions Required

### DO NOT:
- ❌ Push to GitHub without remediation
- ❌ Commit files with hardcoded keys
- ❌ Deploy code with hardcoded keys
- ❌ Share repository publicly

### DO:
- ✅ Review remediation options with team
- ✅ Decide on remediation strategy (Option 1, 2, or 3)
- ✅ Run remediation script OR manually fix
- ✅ Verify all fixes with `grep` scan
- ✅ Test application still works after remediation
- ✅ Rotate API keys if they are real/active keys
- ✅ Update .env.example with placeholders
- ✅ Commit remediated code only

## Verification After Remediation

```bash
# Scan for remaining hardcoded keys
grep -r -i "sk-or-v1\|sk-dBoxml" backend/

# Should return ZERO results (or only .env.example if using placeholders)
# If any results found in code files, continue remediation
```

## Post-Remediation Checklist

- [ ] All hardcoded keys replaced in Python files
- [ ] All hardcoded keys replaced in JSON files
- [ ] .env.example contains only placeholders
- [ ] No secrets in git history (we're starting fresh, so OK)
- [ ] Application tested with environment variables
- [ ] README updated with environment setup instructions
- [ ] .gitignore verified (already created)
- [ ] Final security scan clean
