CVE-2026-75971

Estado: AplazadaAlta (7.2)—

The ShopEngine Elementor WooCommerce Builder Addon – All in One WooCommerce Solution plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9.4. This is due to the `rum_importer()` function being registered on the WordPress core `import_start` action hook with no plugin-owned capability check and no allowlist filtering, causing arbitrary `<wp_option>` name/value pairs parsed from an attacker-supplied WXR import file to be passed directly to `update_option()`.

Leer descripción completaMostrar menos

This makes it possible for authenticated attackers, with Shop Manager-level access and above, to write arbitrary WordPress options — most critically setting `users_can_register` to `1` and `default_role` to `administrator` — enabling open self-registration of Administrator accounts and full site takeover. This is exploitable by Shop Manager-level users because WooCommerce grants that role the `import` capability, allowing it to reach the WordPress Importer flow that fires the `import_start` hook on which `rum_importer()` is registered, contrary to the assumption that the hook is restricted to 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.

Vulnerabilidad en plugin WordPress explotable por usuarios autenticados con acceso remoto a través de función `rum_importer()` que permite escalada de privilegios (crear cuentas administrador). PR:H indica autenticación previa; red sin restricción local; impacto directo en permisos y cuentas.

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.

Esto se debe a que la función 'rum_importer()' está registrada en el hook de acción 'import_start' del núcleo de WordPress sin una verificación de capacidad propiedad del plugin y sin filtrado de lista de permitidos, lo que provoca que pares arbitrarios de nombre/valor <wp_option> analizados desde un archivo de importación WXR suministrado por un atacante se pasen directamente a 'update_option()'. Esto hace posible que atacantes autenticados, con acceso de nivel de Gerente de Tienda y superior, escriban opciones arbitrarias de WordPress - lo más crítico, estableciendo 'users_can_register' en '1' y 'default_role' en 'administrator' - lo que permite el auto-registro abierto de cuentas de Administrador y la toma de control total del sitio. Esto es explotable por usuarios de nivel de Gerente de Tienda porque WooCommerce otorga a ese rol la capacidad 'import', lo que le permite alcanzar el flujo del Importador de WordPress que dispara el hook 'import_start' en el que 'rum_importer()' está registrado, contrario a la suposición de que el hook está restringido a Administradores."
