Top 3 fixes

1. Hardcoded admin credentials — Remove plaintext passwords from _SEED_MEMBERS; inject via env var or one-time setup script.
2. CSP unsafe-inline styles — Replace 'unsafe-inline' in style-src with a nonce or hash-based allowlist.
3. serialize-javascript — Run npm audit fix / update vitest build chain to patch GHSA-5c6j-r48x-rmvq.

Evidence (Critical/High only)

[High] Hardcoded default admin credentials

• Location: backend/app/main.py:47
• Snippet: {"email": "admin@lima-impro.fr", ..., "app_role": "admin", "password": "Admin1234!", ...}
• Impact: Any DB reset or fresh migration auto-creates an admin account with a publicly known password; repo read access = admin compromise.
• Fix: Remove passwords from source; inject hashed credential via env var or interactive first-run prompt.

Verified safe

• No XSS sinks (dangerouslySetInnerHTML, innerHTML, eval) in frontend source
• No hardcoded API keys or bearer tokens in source files
• HSTS: max-age=31536000; includeSubDomains set in nginx.conf
• X-Frame-Options: DENY; X-Content-Type-Options: nosniff; Referrer-Policy set
• TLS 1.0/1.1 disabled; TLS 1.2/1.3 enabled on limaimpro.duckdns.org
• Backend CORS uses explicit allowlist (not wildcard); allow_credentials=True scoped correctly
• PWA workbox: NetworkFirst strategy for API calls; no static cache on auth routes
• Sensitive file probes (.env, .git/config) returned 403
• No postMessage, eval, or open-redirect patterns in React source

Needs server-side verification

• CORS_ORIGINS env var value in Railway production (fallback includes localhost)
• Whether APP_ENV check disables seed data seeding in production runtime
• Actual response headers on live site (sandbox network policy blocked HTTP probes)
• /docs endpoint disabled in production (FastAPI config, unverified remotely)

Tools

ran=openssl-s_client, npm-audit, grep-secrets; skipped=curl-http-probes (sandbox network policy blocked target host)
