Recommendation: Plan a near-term fix — a public PoC already exists.
The WP Support Plus Responsive Ticket System WordPress plugin through 9.1.2 does not sign or verify its guest-session cookie, allowing unauthenticated attackers to forge it and impersonate any ticket owner (identified by email address) to read, reply to, and close that person's support tickets.
