## Description

The Essential Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Custom JS extension's page setting in all versions up to, and including, 6.8.7. This is due to the administrator-only restriction on Custom JS being applied only to Elementor's document save, while the eael_custom_js value in the _elementor_page_settings post meta, which can be written through the REST API by anyone who can edit the post, is copied unescaped into the page's front-end script on a later Elementor save. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary scripts that run whenever a user accesses the page, once the page is published and saved again in Elementor, for example by an administrator.
