CVE-2021-39166

Estado: ModificadaMedia (5.4)—

Pimcore es una plataforma de administración de datos y experiencias de código abierto. En versiones anteriores a 10.1.2, los valores de texto no se escapaban apropiadamente versiones anteriores a imprimirse en la visualización previa de la versión. Esto permitía el uso de un ataque de tipo XSS por parte de usuarios autenticados con acceso a los recursos. Este problema se ha parcheado en Pimcore versión 10.1.2
