Summary
The Webheadcoder Multi-Step Forms for Contact Form 7 plugin for WordPress is affected in all versions up to and including 4.7. Insufficient input sanitization and output escaping of the l10n_print_after parameter causes reflected cross-site scripting (CWE-79). An unauthenticated attacker can inject scripts that run if a user is tricked into clicking a link on a site with a [multistep] Contact Form 7 form.

Description from the CNA
The Webheadcoder Multi-Step Forms for Contact Form 7 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'l10n_print_after' parameter in all versions up to, and including, 4.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Successful exploitation requires that the targeted site has at least one Contact Form 7 form configured with a [multistep] form-tag, as the canonicalization introduced in version 4.7 blocks the attack path on non-multistep forms.
