CyberRota Analysis

AI-Generated

The Kubio AI Page Builder plugin for WordPress is vulnerable to an authorization bypass, allowing authenticated attackers with contributor-level access or higher to manipulate critical front-page settings and navigation elements. This vulnerability arises from inadequate verification of user permissions, as the nonce check can be easily exploited by any user with access to the block editor. WordPress site administrators using this plugin should prioritize patching to mitigate potential unauthorized changes to their site configurations.

Original NVD Description

The Kubio AI Page Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.8.5. 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 contributor-level access and above, to overwrite front-page configuration options (show_on_front, page_on_front, and page_for_posts), rewrite primary navigation menu items, replace template parts, and overwrite the Kubio global-data post. Although a nonce check via check_ajax_referer() is present, the nonce is unconditionally emitted into window.kubioUtilsData for every user who can load the block editor, making it harvestable by any Contributor and therefore an ineffective authorization barrier.
