sécurité : correctifs XSS, SSRF, CSWSH, rate-limit et durcissement
- XSS stocké (critique) : sanitisation bluemonday sur tous les endpoints d'articles (List, ListByFeed, Favorites, Search, Get), pas seulement Get - SSRF (élevé) : nouveau utils/safehttp.go (ValidateExternalURL + client durci via Dialer.Control, bloque IP privées/loopback/link-local/metadata, anti-DNS-rebinding et limite de redirections) appliqué à l'extracteur et au parser - WebSocket CSWSH (élevé) : politique same-origin + override WS_ALLOWED_ORIGINS - rate-limiting (moyen) : token-bucket en mémoire sur /auth/* - token de session retiré du corps JSON (json:"-"), livré uniquement par le cookie HttpOnly - cookie Secure correct derrière un reverse-proxy (X-Forwarded-Proto + override COOKIE_SECURE) - admin : interdiction de supprimer son propre compte - en-têtes de sécurité (nosniff, X-Frame-Options, Referrer-Policy, Permissions-Policy) Note : backend non compilé localement (pas de toolchain Go) ; à valider via Docker.
