Summary
The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' parameter in all versions up to and including 2.3.2 due to insufficient input sanitization and output escaping.
Risk Assessment
An unauthenticated attacker can inject arbitrary web scripts that execute in a victim's browser if they trick the user into clicking a crafted link, potentially leading to session theft, redirection to malicious sites, or data theft.
Recommendation
Immediately update the WP Hotel Booking plugin to version 2.3.3 or later, which contains the fix. Until the update is applied, restrict access to the WordPress admin panel.
Other vulnerabilities in WP Hotel Booking
See all- CVE-2026-15152Medium
The WP Hotel Booking WordPress plugin before 2.3.2 does not verify that a payment notification corresponds to a payment made to the site's own merchant account, nor that the paid amount matches the booking total, allowing unauthenticated users to have their bookings marked as fully paid without any payment reaching the site owner.
- CVE-2026-15149Medium
The WP Hotel Booking WordPress plugin before 2.3.3 does not ensure that room quantities and the resulting order total are non-negative when placing a booking, and relies on client-controlled cart data, allowing unauthenticated users to create confirmed reservations for free or at an arbitrarily reduced price.
- CVE-2026-15464Medium
The WP Hotel Booking plugin for WordPress is vulnerable to Stored XSS via the 'widget_search' Shortcode Attribute due to insufficient input sanitization. Attackers with contributor-level access can inject arbitrary scripts, but exploitation requires browsers supporting access keys.
- CVE-2026-11901Medium
The WP Hotel Booking plugin for WordPress up to version 2.3.1 fails to properly verify data authenticity in the PayPal IPN handler. An attacker can use the `test_ipn` parameter to redirect validation to PayPal sandbox and force upgrade transaction status from 'pending' to 'completed' without actual payment. Missing checks on `txn_id` uniqueness, `receiver_email`, and `mc_currency` after a `VERIFIED` response further enable exploitation.
- CVE-2026-11392Medium
The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' and 'check_out_date' parameters in all versions up to and including 2.3.1 due to insufficient input sanitization and output escaping.
Original NVD description (English source)
The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' parameter in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
