Description
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.11. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to send arbitrary HTML-injected emails — including phishing messages embedding a real, valid WordPress password-reset URL for the targeted user — to any registered user via the site's own mail server, abusing its SPF/DKIM reputation. The attacker-controlled emailSubject parameter is passed to wp_mail() with only sanitize_text_field() applied, while emailBody 'text' items are concatenated raw into the HTML email body with no escaping, and 'chip' items can include the genuine WordPress password-reset link for the targeted account.
