FKIE_CVE-2025-15018

Vulnerability from fkie_nvd - Published: 2026-01-07 12:16 - Updated: 2026-10-07 09:10
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The Optional Email plugin for WordPress is vulnerable to Privilege Escalation via Account Takeover in all versions up to, and including, 1.3.11. This is due to the plugin not restricting its 'random_password' filter to registration contexts, allowing the filter to affect password reset key generation. This makes it possible for unauthenticated attackers to set a known password reset key when initiating a password reset, reset the password of any user including administrators, and gain access to their accounts.

      "value": "El plugin Optional Email para WordPress es vulnerable a escalada de privilegios mediante toma de control de cuenta en todas las versiones hasta la 1.3.11, inclusive. Esto se debe a que el plugin no restringe su filtro \u0027random_password\u0027 a contextos de registro, lo que permite que el filtro afecte la generaci\u00f3n de claves de restablecimiento de contrase\u00f1a. Esto hace posible que atacantes no autenticados establezcan una clave de restablecimiento de contrase\u00f1a conocida al iniciar un restablecimiento de contrase\u00f1a, restablezcan la contrase\u00f1a de cualquier usuario, incluidos los administradores, y obtengan acceso a sus cuentas."
