CVE-2026-109369 6.8 Moyenne
murgroland WP Booking System – Booking Calendar
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.0.3 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to grant themselves and arbitrary other users edit access to every booking form on the site by overwriting the user_permission meta that governs the plugin's own access-control list. Exploitation requires the attacker to have already been delegated edit rights on at least one booking form, as this delegation both downgrades the submenu capability to 'read' (making the edit page accessible) and allows them to harvest a valid wpbs_edit_form nonce that will pass validation against any other form_id.

CVE-2026-109368 6.5 Moyenne
murgroland WP Booking System – Booking Calendar
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.1.0.3 via the 'id' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract private per-event booking descriptions and booking IDs from any calendar managed by the site.

CVE-2026-108123 7.5 Élevée
murgroland WP Booking System – Booking Calendar
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.0.3 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to read the stored notification email body of any booking by iterating booking_id and email_log_id, exposing customer PII including names, email addresses, phone numbers, messages, and booking dates intended to be visible only to administrators. This is exploitable by any Subscriber-level user because admin_init fires on profile.php, a wp-admin page accessible to all authenticated users.

CVE-2026-111178 4.9 Moyenne
murgroland WP Booking System – Booking Calendar
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to generic SQL Injection via the 'data[orderby]' parameter in all versions up to, and including, 2.1.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the targeted calendar to have more than 200 bookings, as the orderby value is only forwarded to the database layer when the AJAX handler takes the use_ajax branch; an Administrator can satisfy this condition by creating bookings directly.

CVE-2026-107712 6.5 Moyenne
murgroland WP Booking System – Booking Calendar
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to time-based SQL Injection via the 'current_month' parameter in all versions up to, and including, 2.1.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a regression vulnerability — a capability check introduced in versions 2.0.19.11–2.0.19.14 to address CVE-2024-50425 was removed in version 2.1, meaning any authenticated subscriber-level account can reach the vulnerable handler with no nonce validation required.
