lib/db/upgrade.php in Moodle 2.0.x before 2.0.5 and 2.1.x before 2.1.2 does not set the correct registration_hubs.secret value during installation, which allows remote attackers to bypass intended access restrictions by leveraging the hubs feature.

Security readout for executives and security teams

This flaw affects old Moodle 2.0 and 2.1 installations. During installation, Moodle could set the hub registration secret incorrectly, letting a remote attacker bypass intended access restrictions through the hubs feature. The sources do not provide a CVSS score or evidence of active exploitation. Exposure is likely limited to legacy Moodle 2.0.x and 2.1.x systems, especially installations using the hubs feature. Modern Moodle deployments are unlikely to be affected unless they retain these old branches or inherited vulnerable database state. Treat this as a legacy-platform risk. Prioritize if the organization still runs Moodle 2.0 or 2.1, especially internet-facing education portals. Otherwise, track as low operational urgency with documentation for asset owners. Mitigation focus: Upgrade affected Moodle 2.0.x systems to 2.0.5 or later.; Upgrade affected Moodle 2.1.x systems to 2.1.2 or later.; Review Moodle vendor guidance and the referenced upstream commit before changing hub secrets..
