Description
mod/lti/launch.php in the LTI module in Moodle through 2.4.11, 2.5.x before 2.5.9, 2.6.x before 2.6.6, and 2.7.x before 2.7.3 performs access control at the course level rather than at the activity level, which allows remote authenticated users to bypass the mod/lti:view capability requirement by viewing an activity instance.
