## Critical Findings

### 1. Session Fixation Vulnerability
**File**: {baseDir}/src/auth/login.js
**Line**: 45
**Issue**: Session ID not regenerated after authentication
**Risk**: Attacker can hijack authenticated session
**Code**:
```javascript
function handleLogin(req, res) {
  if (validateCredentials(req.body)) {
    req.session.authenticated = true;  // VULNERABLE
    res.redirect('/dashboard');
  }
}
```
**Remediation**:
```javascript
function handleLogin(req, res) {
  if (validateCredentials(req.body)) {
    req.session.regenerate((err) => {  // SECURE
      req.session.authenticated = true;
      res.redirect('/dashboard');
    });
  }
}
```

### 2. Missing HttpOnly Flag
**File**: {baseDir}/config/session.js
**Line**: 12
**Issue**: Session cookies accessible to JavaScript
**Risk**: XSS attacks can steal session tokens
**Remediation**: Set `httpOnly: true` in cookie configuration
