CVE-2026-15149 is a medium severity vulnerability in the WP Hotel Booking WordPress plugin before version 2.3.3. The plugin does not properly validate that room quantities and order totals are non-negative during booking. It relies on client-controlled cart data, which allows unauthenticated users to create confirmed reservations for free or at a reduced price.
AI Analysis
Technical Summary
The WP Hotel Booking plugin versions prior to 2.3.3 have an improper input validation vulnerability (CWE-20) where the plugin fails to ensure that room quantities and the resulting order total are non-negative when placing a booking. This flaw allows unauthenticated attackers to manipulate client-side cart data to create confirmed bookings without paying or by paying less than intended. The vulnerability stems from trusting client-controlled data without sufficient server-side validation.
Potential Impact
Unauthenticated attackers can exploit this vulnerability to create confirmed hotel reservations without payment or at a reduced price, potentially causing financial loss to the hotel or booking service. There is no impact on confidentiality or availability reported, but integrity is affected due to unauthorized modification of booking data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor for updates from the WP Hotel Booking plugin vendor and avoid relying on client-side data for critical booking information.
