Descriptions

The Quick Event Manager WordPress Plugin, version < 9.7.5, is affected by a reflected cross-site scripting vulnerability in the 'category' parameter of its 'qem_ajax_calendar' action.

El complemento Quick Event Manager de WordPress, versión < 9.7.5, se ve afectado por una vulnerabilidad de cross site scripting reflejado en el parámetro 'category' de su acción 'qem_ajax_calendar'.

The Quick Event Manager WordPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 9.7.4 via the 'category' parameter of the 'qem_ajax_calendar' action 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.
