Descriptions

The Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions plugin for WordPress is vulnerable to unauthorized modification of membership levels created by the plugin due to an incorrectly implemented capability check in the pmpro_rest_api_get_permissions_check function in all versions up to 2.12.5 (inclusive). This makes it possible for unauthenticated attackers to change membership levels including prices.

El complemento Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions para WordPress es vulnerable a modificaciones no autorizadas de los niveles de membresía creados por el complemento debido a una verificación de capacidad implementada incorrectamente en la función pmpro_rest_api_get_permissions_check en todas las versiones hasta 2.12.5 (incluida). Esto hace posible que atacantes no autenticados cambien los niveles de membresía, incluidos los precios.
