 # Remaining Security Issues
 
-1. **No rate limiting on `/reauth`** — brute-force possible via export dialog
-2. **No Content Security Policy (CSP)** header — XSS could leak crypto key from sessionStorage
+1. ~~**No rate limiting on `/reauth`** — brute-force possible via export dialog~~ ✅
+2. ~~**No Content Security Policy (CSP)** header — XSS could leak crypto key from sessionStorage~~ ✅
 3. **Crypto key in sessionStorage (extractable)** — necessary for refresh persistence, but XSS can steal it. HttpOnly cookie + service worker is more secure but complex
-4. **No session rotation** — same token until logout; if leaked, valid for 24h
+4. ~~**No session rotation** — same token until logout; if leaked, valid for 24h~~ ✅
 5. **No 2FA** — opted out of TOTP implementation
-6. **Password generator modulo bias** — `c.charAt(arr[i] % c.length)` has slight bias when c.length does not divide 2^32; not practically exploitable
