CVE-2024-48900Network attack vector

Badge-recipient disclosure via incorrect context check

Published Nov 13, 2024 · Updated Nov 21, 2024

Authorization bypass in Moodle LMS 4.4.0 through 4.4.3 allows remote authenticated users to view unauthorized badge-recipient lists. The badge-recipient report builder checks moodle/badges:viewawarded against the report context instead of the selected badge context. A user permitted to view awarded badges in one context can supply another badge identifier and read its recipient list without authorization to that badge.
