CVE-2026-6898

Estado: AplazadaAlta (8.8)—

The Wishlist Member plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'WishListMember3_Hooks::generate_api_key' function in all versions up to, and including, 3.30.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the REST API Secret Key, which can be used to create a new membership level assigned the administrator WordPress role, and register an arbitrary administrator-level user account, resulting in complete site takeover.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad remota que requiere autenticación (PR:L) en servicio web (AV:N). Permite a atacante autenticado generar claves API y crear cuentas admin (T1068 escalada, T1098 creación de cuentas, T1078 uso de credenciales válidas). CWE-269: falta validación de permisos.
