CVE-2021-24208: WP Page Builder < 1.2.4 - Multiple Stored Cross-Site scripting (XSS)
The editor of the WP Page Builder WordPress plugin before 1.2.4 allows lower-privileged users to insert unfiltered HTML, including JavaScript, into pages via the “Raw HTML” widget and the “Custom HTML” widgets (though the custom HTML widget requires sending a crafted request - it appears that this widget uses some form of client side validation but not server side validation), all of which are added via the “pagebuilderdata” parameter when performing the “wppbpagesave” AJAX action. It is also possible to insert malicious JavaScript via the “wppbpagecss” parameter (this can be done by closing out the style tag and opening a script tag) when performing the “wppbpagesave” AJAX action.
