User-profile disclosure via null-ticket authorization bypass
Published Apr 14, 2025 · Updated Apr 14, 2025
Improper authorization in Jcool98 Echo 4.2 allows remote attackers to read user profile information through protected web routes. LoginTicketInterceptor.preHandle checks a ticket only when the cookie value is non-null, then always returns true, so a missing ticket bypasses the intended gate. An unauthenticated GET request can reach protected profile handlers and disclose other users’ profile data; no write or service-interruption impact is documented.
