description

Hotel Booking through version 3.8 lacks request-origin validation for administrative booking-order actions. An attacker may cause a logged-in administrator to create, alter, or remove booking orders after inducing that administrator to interact with attacker-controlled content.

mitigation

Disable the Hotel Booking plugin until a vendor release with CSRF protections is available. If it must remain deployed, limit administrative access and keep administrators from accessing untrusted content while authenticated.

outcome

Upstream: a detection for this already ships elsewhere, so we didn't generate a new one. The credit goes to whoever did.
