Authenticated stored XSS via unprotected AJAX settings
Published Apr 7, 2020 · Updated Aug 4, 2024
Stored XSS in Contact Form 7 Datepicker through 2.6.0 allows remote authenticated users to store JavaScript via an unprotected AJAX action. The wp_ajax_cf7dp_save_settings handler accepts the ui_theme parameter without capability or nonce checks and persists attacker-controlled script in plugin settings. When an administrator creates or edits a contact form, the script runs in the administrator browser and can create administrative users or perform actions with that session.
