CyberRota Analysis

AI-Generated

The Kubio AI Page Builder plugin for WordPress prior to version 2.9.3 is vulnerable due to improper filtering of HTML elements, allowing unauthenticated users to inject malicious markup. This can lead to stored cross-site scripting (XSS) attacks, where the injected scripts are executed in the browsers of visitors or administrators reviewing submissions. WordPress site administrators using this plugin should prioritize updating to the latest version to mitigate potential security risks.

Original NVD Description

The Kubio AI Page Builder WordPress plugin before 2.9.3 does not limit its widening of the allowed HTML elements to the editor context, so the wider set is applied when filtering content submitted by unauthenticated users as well, allowing them to store markup which the Kubio AI Page Builder WordPress plugin before 2.9.3's own script later executes in the browser of any visitor, or of an administrator reviewing the still-unapproved submission.
