Stored XSS via unchecked AJAX settings update

Published Mar 14, 2022 · Updated Aug 3, 2024

The meks_save_business_selected_account AJAX action lacks capability and CSRF checks and stores unescaped access_token input in plugin settings. Subscriber access is sufficient to submit the payload, but execution requires an administrator to open the plugin settings page.
