CVE-2015-5339: Exposure of Sensitive Information to an Unauthorized Actor

May 13, 2022 (updated January 26, 2024)

The core_enrol_get_enrolled_users web service in enrol/externallib.php in Moodle through 2.6.11, 2.7.x before 2.7.11, 2.8.x before 2.8.9, and 2.9.x before 2.9.3 does not properly implement group-based access restrictions, which allows remote authenticated users to obtain sensitive course-participant information via a web-service request.
