CVE-2022-0984Network attack vector

Course badge manipulation via site-only profile criteria

Published Apr 29, 2022 · Updated Aug 2, 2024

Incorrect authorization in Moodle LMS allows remote authenticated users to add site-only profile-field criteria to course badges. The badge-criteria configuration path exposes and accepts the profile criterion for course-scoped badges without enforcing its site-badge-only restriction. Access requires the moodle/badges:configurecriteria capability, granted to teachers and managers by default, and permits unauthorized badge-rule changes without reported data disclosure or service interruption.
