Description
The Royal Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Instagram Feed widget's 'instagram_follow_text' setting in all versions up to, and including, 1.7.1056 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Note that exploitation requires that an administrator has previously configured the Instagram Feed widget with a valid Instagram access token on the site.
