What is CVE-2026-15149?

The WP Hotel Booking plugin prior to version 2.3.3 includes a critical input validation flaw, where it fails to ensure that room quantities and order totals are non-negative. This oversight permits unauthenticated users to manipulate cart data, potentially allowing them to secure confirmed reservations without payment or at significantly reduced prices. Implementing the latest updates is crucial to mitigate the risk associated with this vulnerability.
