Informations générales

Ceci ne concerne que les versions Joomla! : 3.8.4+

Module Chromes (CVE-2018-6380)

This patch is fixing a longstanding issue with the module Chrome where the module_tag parameter in the system and Protostar template lack escaping which could lead to a XSS attack. This issue is fixed in Joomla 3.8.4 but only for the core templates. Please contact your template provider so they can check the corresponding module Chromes.

com_fields (CVE-2018-6377)

This patch fixes a problem where you can enter a XSS code to the Text / Value options in com_fields plugins, like Checkbox, Radio and List. As a side effect of not allowing XSS anymore, the com_fields labels can't be anymore outputted as html.
