Résumé
React Router: RSCErrorHandler Missing Protocol Validation (XSS)
Détails de l’avis
This is a follow up to https://github.com/remix-run/react-router/security/advisories/GHSA-8646-j5j9-6r62. React Router was alerted of a code path in the (unstable) RSC error handling path in which redirects from untrusted sources could still result in an XSS vector via attacker-supplied redirect targets
[!NOTE] This only affects your application if you are using the unstable RSC APIs
