## Description

The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via bdt-* and data-bdt-* UIkit component attributes in post and Elementor content in versions 8.8.7 up to, and including, 8.8.9, due to the Content Guard filter only stripping these attributes when whitespace comes before them. An attribute that follows a "/" (for example <span class="a"/data-bdt-svg="...">) gets past the filter and is then turned into a valid attribute by wp_kses. This makes it possible for authenticated attackers, with contributor-level access and above, to start UIkit components such as the SVG loader and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
