Vulnerability from fkie_nvd - Published: 2026-01-24 13:15 - Updated: 2026-01-26 15:03
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
The Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to arbitrary file uploads due to incorrect file type validation in the action_import_module() function in all versions up to, and including, 7.8.9.2. This makes it possible for authenticated attackers, with a lower-privileged role (e.g., Subscriber-level access and above), to upload arbitrary files on the affected site's server which may make remote code execution possible. Successful exploitation requires an admin to grant Hustle module permissions (or module edit access) to the low-privileged user so they can access the Hustle admin page and obtain the required nonce.

La explotaci\u00f3n exitosa requiere que un administrador otorgue permisos del m\u00f3dulo Hustle (o acceso de edici\u00f3n de m\u00f3dulo) al usuario de bajo privilegio para que puedan acceder a la p\u00e1gina de administraci\u00f3n de Hustle y obtener el nonce requerido."
