CVE-2018-1136: Cross-site Scripting

May 25, 2018 (updated October 3, 2019)

An issue was discovered in Moodle. An authenticated user is allowed to add HTML blocks containing scripts to their Dashboard; this is normally not a security issue because a personal dashboard is visible to this user only. Through this security vulnerability, users can move such a block to other pages where they can be viewed by other users.
