Contributor-level site and taxonomy manipulation via unchecked routes
Published Sep 5, 2026 · Updated Sep 6, 2026
Missing authorization in Arraytics Eventin before 4.1.22 allows remote authenticated users to alter site and taxonomy data through REST routes. Several event-management routes fail to verify event ownership or authority to manage global event and speaker taxonomy terms. Contributor-level access is sufficient to replace the site's front page with an unowned event and create, edit, or delete shared terms.
