CVE-2026-11823
BookingPress Appointment Booking Pro <= 5.7.1 - Unauthenticated SQL Injection via 'store_service_date' Parameter
Description
The BookingPress Appointment Booking Pro plugin for WordPress is vulnerable to SQL Injection via the 'store_service_date' parameter of the bpa_assign_staffmember_to_slots() function in versions up to and including 5.7.1. This is due to the explicit use of stripslashes_deep() on user-supplied POST data before it is interpolated verbatim into a SQL LIKE clause without use of $wpdb->prepare() or any parameterization. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Action Type Old Value New Value Added Translation Title: plugin BookingPress Appointment Booking Pro de Repute Infosystems para WordPress, Description: El plugin BookingPress Appointment Booking Pro para WordPress es vulnerable a inyección SQL a través del parámetro ’store_service_date’ de la función bpa_assign_staffmember_to_slots() en versiones hasta la 5.7.1 inclusive. Esto se debe al uso explícito de stripslashes_deep() en datos POST proporcionados por el usuario antes de que se interpolen textualmente en una cláusula SQL LIKE sin el uso de $wpdb -> prepare() ni ninguna parametrización. Esto hace posible que atacantes no autenticados añadan consultas SQL adicionales a consultas ya existentes que pueden usarse para extraer información sensible de la base de datos. -
