Descriptions

Contao is an open source content management system. Starting in version 4.0.0 and prior to version 4.13.40 and 5.3.4, it is possible to inject insert tags in frontend forms if the output is structured in a very specific way. Contao versions 4.13.40 and 5.3.4 have a patch for this issue. As a workaround, do not output user data from frontend forms next to each other, always separate them by at least one character.

Contao es un sistema de gestión de contenidos de código abierto. A partir de la versión 4.0.0 y antes de la versión 4.13.40 y 5.3.4, es posible inyectar etiquetas de inserción en formularios de interfaz si la salida está estructurada de una manera muy específica. Las versiones 4.13.40 y 5.3.4 de Contao tienen un parche para este problema. Como workaround, no genere datos de usuario desde formularios de interfaz uno al lado del otro, sepárelos siempre con al menos un carácter.
