FKIE_CVE-2026-3226

Vulnerability from fkie_nvd - Published: 2026-03-12 03:15 - Updated: 2026-03-12 21:07
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 LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized email notification triggering due to missing capability checks on all 10 functions in the SendEmailAjax class in all versions up to, and including, 4.3.2.8. The AbstractAjax::catch_lp_ajax() dispatcher verifies a wp_rest nonce but performs no current_user_can() check before dispatching to handler functions. The wp_rest nonce is embedded in the frontend JavaScript for all authenticated users. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger arbitrary email notifications to admins, instructors, and users, enabling email flooding, social engineering, and impersonation of admin decisions regarding instructor requests.

El despachador AbstractAjax::catch_lp_ajax() verifica un nonce wp_rest pero no realiza ninguna comprobaci\u00f3n current_user_can() antes de despachar a las funciones gestoras. El nonce wp_rest est\u00e1 incrustado en el JavaScript de frontend para todos los usuarios autenticados. Esto hace posible que atacantes autenticados, con acceso de nivel Suscriptor y superior, activen notificaciones de correo electr\u00f3nico arbitrarias a administradores, instructores y usuarios, lo que permite el env\u00edo masivo de correos electr\u00f3nicos (email flooding), la ingenier\u00eda social y la suplantaci\u00f3n de decisiones administrativas con respecto a las solicitudes de los instructores."
