## Critical Action Items
|
|
|
|
### This Week (Priority: CRITICAL)
|
|
|
|
1. **Fix XSS Vulnerabilities**
|
|
- [ ] `backend/app/static/js/dashboard.js` line 234 - Replace `innerHTML` with safe DOM methods
|
|
- [ ] `backend/app/static/js/dashboard.js` line 15 - Use `textContent` instead
|
|
- [ ] `backend/app/static/js/login.js` line 9 - Use safe DOM methods
|
|
- [ ] `backend/app/static/js/setup.js` line 9 - Use `textContent` instead
|
|
|
|
2. **Fix Credential Storage**
|
|
- [ ] `backend/app/static/js/setup.js` lines 188-189 - Remove localStorage, send to backend
|
|
|
|
3. **Fix CSP Violations**
|
|
- [ ] `backend/app/templates/daisy-demo.html` line 274 - Remove inline onclick handler
|
|
|
