Descriptions

The Booking Calendar WordPress plugin before 9.7.3.1 does not sanitize and escape some of its booking from data, allowing unauthenticated users to perform Stored Cross-Site Scripting attacks against administrators

El complemento de WordPress Booking Calendar anterior a la versión 9.7.3.1 no sanitiza ni escapa algunas de sus reservas de los datos, lo que permite a usuarios no autenticados realizar ataques de Cross-Site Scripting (XSS) Almacenado contra administradores.

The Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the booking form fields in versions up to, and including, 9.7.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
