It is possible to schedule/trigger/unschedule existing jobs by having an admin visit the Job Scheduler page through a predictable URL, for example by embedding such an URL in any content as an image.
To reproduce in an XWiki installation, open <xwiki-host>:/xwiki/bin/view/Scheduler/?do=trigger&which=Scheduler.NotificationEmailDailySender as a user with admin rights. If there is no error message that indicates the CSRF token is invalid, the installation is vulnerable.
The vulnerability has been fixed on XWiki 14.10.19, 15.5.5, and 15.9.
