Vulnerability from fkie_nvd - Published: 2026-02-19 07:17 - Updated: 2026-04-15 00:35
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Summary
The Shield Security plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 21.0.8. This is due to the plugin allowing nonce verification to be bypassed via user-supplied parameter in the 'isNonceVerifyRequired' function. This makes it possible for unauthenticated attackers to execute SQL injection attacks, extracting sensitive information from the database, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Esto hace posible que atacantes no autenticados ejecuten ataques de inyecci\u00f3n SQL, extrayendo informaci\u00f3n sensible de la base de datos, a trav\u00e9s de una petici\u00f3n falsificada siempre que puedan enga\u00f1ar a un administrador del sitio para que realice una acci\u00f3n como hacer clic en un enlace."
