CVE-2025-26532Network attack vector

Teacher content-filter bypass via glossary restoration

Published Feb 24, 2025 · Updated Feb 25, 2025

Incorrect authorization in Moodle LMS allows remote authenticated users to bypass trusttext checks during glossary restoration. The glossary-entry restore path accepts entry text without consistently reapplying trusttext when that site option is enabled. Teacher-level course-restore permission is required, and the documented effect is limited to unauthorized content changes.
