CyberRota Analysis

AI-Generated

The Everest Forms plugin for WordPress is vulnerable to an authorization bypass that allows authenticated attackers with delegated form management access to activate any installed WordPress plugins, including those that are deactivated or known to be vulnerable. This flaw arises from inadequate verification of user permissions, enabling exploitation by users assigned specific roles, such as Author, who can access the necessary AJAX handlers. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of unauthorized plugin activation and potential exploitation.

Original NVD Description

The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.5.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with delegated form management access and above, to activate arbitrary already-installed WordPress plugins — including previously deactivated or vulnerable plugins — without holding the core activate_plugins capability. Exploitation requires the target user to hold a delegated Everest Forms capability (manage_everest_forms, everest_forms_create_forms, or everest_forms_view_forms), which the plugin's own roles and permissions tool allows administrators to assign to non-administrator roles such as Author; the nonces required to exploit the AJAX handlers are emitted on EVF admin pages accessible to any such delegated user.
