Vulnerability from fkie_nvd - Published: 2026-01-24 08:16 - Updated: 2026-06-17 10:14
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
Summary
The Set Bulk Post Categories plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. This is due to missing nonce validation on the bulk category update functionality. This makes it possible for unauthenticated attackers to modify post categories in bulk via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

      "value": "El plugin Set Bulk Post Categories para WordPress es vulnerable a la falsificaci\u00f3n de petici\u00f3n en sitios cruzados en todas las versiones hasta la 1.1, inclusive. Esto se debe a la falta de validaci\u00f3n de nonce en la funcionalidad de actualizaci\u00f3n masiva de categor\u00edas. Esto hace posible que atacantes no autenticados modifiquen categor\u00edas de entradas de forma masiva 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."
