# 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)
