| Description | The Awesome Support – WordPress HelpDesk & Support Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'gdpr-data' parameter in all versions up to, and including, 6.4.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by Subscriber-level users against other accounts because the AJAX handlers accept an arbitrary gdpr-user ID without verifying it belongs to the requester, and the required wpas-gdpr-nonce is emitted via wp_localize_script to every logged-in user on frontend plugin pages and on /wp-admin/profile.php. |
