Descriptions

The Calendar Event Multi View WordPress plugin before 1.4.07 does not have any authorisation and CSRF checks in place when creating an event, and is also lacking sanitisation as well as escaping in some of the event fields. This could allow unauthenticated attackers to create arbitrary events and put Cross-Site Scripting payloads in it.

El plugin de WordPress Calendar Event Multi View anterior a la versión 1.4.07 no dispone de comprobaciones de autorización y CSRF cuando se crea un evento, y también carece de sanitización así como de escapes en algunos de los campos del evento. Esto podría permitir a los atacantes no autentificados crear eventos arbitrarios y poner cargas útiles de Cross-Site Scripting en él

The Calendar Event Multi View plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on event creation and deletion in versions up to, and including, 1.4.06 . This makes it possible for unauthenticated attackers to manipulate events. Additionally, some of the event fields do not undergo proper sanitization leading to the potential of Stored Cross-Site Scripting.

Calendar Event Multi View version 1.4.07 suffers from a cross site scripting vulnerability.
