Description
The Plus Addons for Elementor plugin for WordPress was vulnerable to Authenticated (Contributor+) Stored Cross-Site Scripting via the Button widget's `custom_attributes` setting in versions up to and including 6.4.11. The `render` function in `modules/widgets/tp_button.php` passed the raw `custom_attributes` string through `tp_senitize_js_input()`. This filter is bypassable. The issue is patched in version 6.4.12.
