lib/modinfolib.php in Moodle 2.0.x before 2.0.10, 2.1.x before 2.1.7, 2.2.x before 2.2.4, and 2.3.x before 2.3.1 does not check for a group-membership requirement when determining whether an activity is unavailable or hidden, which allows remote authenticated users to bypass intended access restrictions by selecting an activity that is configured for a group of other users.

Security readout for executives and security teams

Moodle had an access-control flaw where logged-in users could reach activities intended for another group. The business risk is unauthorized viewing or interaction with restricted course activities, especially where group separation supports privacy, assessment integrity, or paid access boundaries. Exposure is limited to Moodle deployments running 2.0.x before 2.0.10, 2.1.x before 2.1.7, 2.2.x before 2.2.4, or 2.3.x before 2.3.1, where activities rely on group-based restricted access. Prioritize remediation where Moodle separates students, customers, cohorts, exams, paid content, or confidential materials by group. The issue is not evidenced as actively exploited, but it directly weakens access controls. Mitigation focus: Upgrade Moodle to the fixed branch version or later.; Check Moodle guidance and MDL-33466 for applicable backports.; Review activities using group-based restricted access..
