CVE-2026-8610
TypeSquare Webfonts for ConoHa <= 2.0.4 - Missing Authorization to Authenticated (Subscriber+) Plugin Settings Modification via 'fontThemeUseType' Parameter
Description
The TypeSquare Webfonts for ConoHa plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.0.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify the plugin's site-wide font settings, including the typesquare_auth option (fontThemeUseType), show_post_form, and typesquare_fonttheme, by submitting a POST request to any wp-admin page. For fontThemeUseType values 1 and 3, no nonce verification is performed either, meaning those branches are additionally exploitable via cross-site request forgery.

Action Type Old Value New Value Added Translation Title: plugin de WordPress TypeSquare Webfonts for ConoHa, Description: El plugin TypeSquare Webfonts for ConoHa para WordPress es vulnerable a una omisión de autorización en todas las versiones hasta la 2.0.4, inclusive. Esto se debe a que el plugin no verifica correctamente que un usuario está autorizado para realizar una acción. Esto hace posible que atacantes autenticados, con acceso de nivel de suscriptor y superior, modifiquen la configuración de fuente de todo el sitio del plugin, incluyendo la opción typesquare_auth (fontThemeUseType), show_post_form y typesquare_fonttheme, al enviar una petición POST a cualquier página de wp-admin. Para los valores 1 y 3 de fontThemeUseType, tampoco se realiza ninguna verificación de nonce, lo que significa que esas ramas son adicionalmente explotables a través de falsificación de petición en sitios cruzados. -
