FKIE_CVE-2026-8610

Vulnerability from fkie_nvd - Published: 2026-05-20 02:16 - Updated: 2026-05-20 13:54
Severity ?
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Summary
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.
