Prior to 7.1.0, a stored cross-site scripting issue affects the Directory Reports form fields set from config, Person editor defaults rendered into address fields, and external self-registration form defaults. This is primarily an admin-to-admin stored XSS path where writable configuration fields are abused. This vulnerability is fixed in 7.1.0."

Antes de la 7.1.0, un problema de cross-site scripting almacenado afecta a los campos del formulario de Informes de Directorio configurados desde la configuración, los valores predeterminados del editor de Personas renderizados en los campos de dirección y los valores predeterminados del formulario de auto-registro externo. Esto es principalmente una ruta de XSS almacenado de administrador a administrador donde se abusan de los campos de configuración escribibles. Esta vulnerabilidad está corregida en la 7.1.0."
