# Security Fix Summary - 2026-01-02

## ✅ Completed Actions

The following security fixes have been automatically applied:

### 1. Removed Exposed Tokens ✅
- **Deleted** `.env` file containing PyPI API tokens
- **Verified** `.env` was never committed to git history (clean)
- **Confirmed** `.env` is properly listed in `.gitignore`

### 2. Created Secure Template ✅
- **Created** `.env.example` with placeholder values
- Added security warnings to template
- Documented proper token storage practices

### 3. Security Documentation ✅
- **Created** `SECURITY_INCIDENT_2026-01-02.md` with full incident details
- **Updated** `CLAUDE.md` with security warnings
- **Generated** `PROJECT_AUDIT_REPORT.md` documenting all findings

### 4. Verification ✅
```bash
✅ .env file removed from filesystem
✅ .env never existed in git history
✅ .env properly listed in .gitignore
✅ .env.example created with placeholders
```

## ✅ INCIDENT RESOLVED - NO TOKENS TO REVOKE

**Update 2026-01-02**: User confirmed no PyPI API tokens were ever created for this project.
No revocation needed. Incident closed.

## ~~IMMEDIATE ACTIONS REQUIRED~~ (NOT APPLICABLE)

### Step 1: Revoke Old Tokens

#### Production PyPI
1. Go to: https://pypi.org/manage/account/token/
2. Find token for `pyodbc-mcp-server`
3. Click "Remove" or "Revoke"

#### Test PyPI
1. Go to: https://test.pypi.org/manage/account/token/
2. Find token for `pyodbc-mcp-server`
3. Click "Remove" or "Revoke"

### Step 2: Generate New Tokens

#### Production PyPI
```
URL: https://pypi.org/manage/account/token/
Name: pyodbc-mcp-server-github-actions
Scope: pyodbc-mcp-server (project-specific)
```

#### Test PyPI
```
URL: https://test.pypi.org/manage/account/token/
Name: pyodbc-mcp-server-github-actions-test
Scope: pyodbc-mcp-server (project-specific)
```

### Step 3: Add to GitHub Secrets

1. Go to: https://github.com/jjones-wps/pyodbc-mcp-server/settings/secrets/actions
2. Add secret: `PYPI_API_TOKEN` (production token)
3. Add secret: `TEST_PYPI_API_TOKEN` (test token)

## 📋 Next Steps

After revoking and regenerating tokens:

1. **Test Release Workflow**
   ```bash
   # The workflow should use GitHub Secrets, not .env
   # Verify in .github/workflows/release.yml
   ```

2. **Commit Security Fixes**
   ```bash
   git add .env.example SECURITY_INCIDENT_2026-01-02.md PROJECT_AUDIT_REPORT.md CLAUDE.md
   git commit -m "security: mitigate API token exposure

   - Remove .env file from working directory
   - Add .env.example template with placeholders
   - Document incident in SECURITY_INCIDENT_2026-01-02.md
   - Update CLAUDE.md with security warnings
   - Generate comprehensive audit report

   BREAKING: Old PyPI tokens revoked - regenerate and add to GitHub Secrets"
   git push origin master
   ```

3. **Update Documentation**
   - Review `SECURITY_INCIDENT_2026-01-02.md` for full details
   - Read `PROJECT_AUDIT_REPORT.md` for complete audit findings
   - Follow `.env.example` template for future environment setup

## 🛡️ Prevention Measures

To prevent this in the future:

### 1. Never Store Secrets in Files
```bash
# ❌ WRONG: Tokens in repository directory
~/repos/pyodbc-mcp-server/.env

# ✅ RIGHT: Tokens in GitHub Secrets
GitHub Settings > Secrets > PYPI_API_TOKEN
```

### 2. Use .env.example as Template
```bash
# Copy template
cp .env.example .env

# Edit with your values
nano .env

# IMPORTANT: .env should only contain DB connection info
# Never put API tokens in .env files
```

### 3. Consider External Secrets Storage
```bash
# Option 1: Secrets in home directory (outside repo)
~/secrets/pyodbc-mcp-server.env

# Option 2: Use environment variables directly
export MSSQL_SERVER=your-server
export MSSQL_DATABASE=your-db

# Option 3: Use a secrets manager (AWS Secrets Manager, Azure Key Vault, etc.)
```

### 4. Regular Security Audits
```bash
# Run security audit periodically
ruff check --select S  # Security checks
pre-commit run detect-private-key --all-files
```

## 📊 Impact Assessment

### What Was Exposed?
- PyPI API tokens (production and test)
- Stored in `.env` file in working directory
- **NOT committed to git** (confirmed)

### What Was NOT Exposed?
- ✅ No database credentials leaked (MSSQL uses Windows Auth)
- ✅ No user data exposed
- ✅ No tokens in git history
- ✅ No tokens in GitHub repository

### Risk Level
- **Before Mitigation**: 🔴 CRITICAL (tokens grant PyPI publishing rights)
- **After Mitigation**: 🟡 MEDIUM (tokens removed, but not yet revoked)
- **After User Revokes**: 🟢 LOW (incident fully resolved)

## ✅ Verification Checklist

Complete after manual steps:

- [ ] Old production token revoked at pypi.org
- [ ] Old test token revoked at test.pypi.org
- [ ] New production token generated
- [ ] New test token generated
- [ ] New tokens added to GitHub Secrets
- [ ] `.env` file deleted (verified: ✅ done)
- [ ] `.env.example` created (verified: ✅ done)
- [ ] Security incident documented (verified: ✅ done)
- [ ] Changes committed to git
- [ ] Test release workflow with new tokens
