Issues remain status:open intentionally — the code fixes are uncommitted-then-committed working-tree changes per repo and aren't "resolved" until merged/deployed.

Frontend: no Content-Security-Policy header in Next.js config
Severity: medium Domain: Security Labels: security, frontend, csp
Description
next.config.ts:29 does not set a Content-Security-Policy header. Without CSP, XSS attacks have unrestricted script execution, making token theft (localStorage) and DOM-based attacks much easier.
Options
- Ship
Content-Security-Policy-Report-Onlyfirst to collect violations, then enforce — safe rollout. - Enforce a moderate CSP allowing required hosts (Telegram, WalletConnect, Mapbox, Sentry) with nonces for inline scripts.
- Strict CSP with nonces and removal of all inline scripts — strongest but requires refactoring
layout.tsxinline scripts.
Recommendation
Ship Content-Security-Policy-Report-Only first, gather violations for a week, then enforce. Inline scripts in layout.tsx must move to nonces. Non-trivial rollout.
Affected Files
