CVE-2018-1136
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.
Does this matter?
Lower severity and a low EPSS score (1.06%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in Moodle 3.x. 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.
