Published Nov 1, 2024 · Updated Apr 28, 2026

Missing authorization in TypeSquare Webfonts 2.0.7 and earlier allows remote attackers to update the WordPress font list. The typesquare_admin_init() function processes the font-list update without checking whether the caller has the required WordPress capability.
