Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A flaw was found in Moodle. When enrolling a user into a course while selecting a group, a check that the selected group actually belonged to that course was missing, allowing a teacher to add users to groups in courses the teacher could not otherwise access.
