What is CVE-2026-15147?

The Five Star Restaurant Reservations plugin for WordPress prior to version 2.7.23 contains a flaw in its handling of payment notifications. It does not properly authenticate incoming payment messages, allowing unauthorized actors to manipulate existing reservations. Attackers can mark any pending reservation as paid and confirmed without proper validation of payment details such as recipient, amount, or status. This oversight can lead to significant financial discrepancies and unauthorized access to valuable customer information.
