 "title": "Contact Form 7 Multi-Step Forms <= 4.7 - Unauthenticated Reflected Cross-Site Scripting via 'l10n_print_after' Form Field",
 "description": "The Webheadcoder Multi-Step Forms for Contact Form 7 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'l10n_print_after' form field in all versions up to, and including, 4.7. This is because form data saved between steps (in the cf7msm_posted_data cookie or the PHP session) is passed to wp_localize_script() without the reserved 'l10n_print_after' key being removed, and WordPress prints that key's value as raw JavaScript. This makes it possible for unauthenticated attackers to run arbitrary script in a victim's browser on pages that load the plugin's script, if they can trick the victim into submitting a crafted multi-step form request.",
