Descriptions

The FluentSMTP WordPress plugin before 2.0.1 does not sanitize parameters before storing the settings in the database, nor does the plugin escape the values before outputting them when viewing the SMTP settings set by this plugin, leading to a stored cross site scripting (XSS) vulnerability. Only users with roles capable of managing plugins can modify the plugin's settings.

El plugin de WordPress FluentSMTP versiones anteriores a 2.0.1, no sanea los parámetros antes de almacenar la configuración en la base de datos, ni escapa de los valores antes de emitirlos cuando se visualiza la configuración SMTP establecida por este plugin, conllevando a una vulnerabilidad de tipo cross site scripting (XSS) almacenado. Sólo usuarios con roles capaces de administrar plugins pueden modificar la configuración del plugin.
