CVE-2026-11875Public exploitNetwork attack vector

Unauthenticated ticket impersonation via unsigned session cookie

Published Jul 9, 2026 · Updated Jul 9, 2026

Authorization bypass in WP Support Plus Responsive Ticket System through 9.1.2 allows remote attackers to access guest tickets. The guest-session cookie treats an attacker-supplied email address as a ticket-owner identity without a signature or integrity verification. No account is required; knowing a ticket owner’s email address permits reading, replying to, and closing that owner’s support tickets.
