CVE-2026-4290

Estado: AplazadaCrítica (9.1)—

The WP Travel Pro plugin for WordPress is vulnerable to arbitrary user deletion via the /wp-json/wp-travel/v1/travel-guide/{user_id} REST API endpoint in all versions up to, and including, 10.6.0. This is due to the check_permission() callback unconditionally returning true and the Database::delete() method passing the user ID directly to wp_delete_user() without any role validation. This makes it possible for unauthenticated attackers to delete arbitrary user accounts, including those of administrators.

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.

Plugin expone REST API sin autenticación (AV:N, PR:N, UI:N) permitiendo eliminar cuentas administrativas. Impacto: manipulación de cuentas y potencial denegación de servicio.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
