Description OSIDB Bzimport 2026-09-29 20:37:33 UTC
A flaw was found in Moodle. User list filters did not respect user profile field visibility settings, allowing a manager to filter by a profile field they could not otherwise view on a user's profile, resulting in partial, inference-based information disclosure.
