Description OSIDB Bzimport 2026-09-29 20:37:17 UTC 
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.
