Persistent XSS in /course/modedit.php of Moodle through 3.7.2 allows authenticated users (Teacher and above) to inject JavaScript into the session of another user (e.g., enrolled student or site administrator) via the introeditor[text] parameter. NOTE: the discoverer and vendor disagree on whether Moodle customers have a reasonable expectation that anyone authenticated as a Teacher can be trusted with the ability to add arbitrary JavaScript (this ability is not documented on Moodle's Teacher_role page). Because the vendor has this expectation, they have stated "this report has been closed as a false positive, and not a bug."

A vulnerability was found in Moodle versions 3.7.x before 3.7.3, 3.6.x before 3.6.7 and 3.5.x before 3.5.9. When a cohort role assignment was removed, the associated capabilities were not being revoked (where applicable).
