Description OSIDB Bzimport 2026-11-06 08:58:57 UTC 
A flaw was found in Moodle's H5P content handling. Insufficient access checks on H5P content files, including extracted and repackaged content stored in the system context and files belonging to hidden or unavailable course modules, could allow users, including those who were not logged in, to view H5P content they did not have permission to access.
