What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The TrueBooker WordPress plugin before 1.3.0 does not verify that the requester owns a booking before rendering its confirmation summary, allowing unauthenticated attackers to enumerate booking identifiers and retrieve the personal information of customers who booked an appointment, as well as invalidate the customer's own confirmation link.
