NO FIX YET · SEE WHAT TO DO
The Slim Jetpack WordPress plugin up to version 2.7.0.1 does not sanitize the website field of its contact form. An unauthenticated visitor can submit a script through a page containing the [contact-form] shortcode, and it runs in the browser of anyone who opens that page.

WordPress sites running the Slim Jetpack plugin (up to 2.7.0.1, the only range Wordfence lists) with a public page that uses the [contact-form] shortcode. Any visitor can store a script through the Website field, and it runs in the browser of whoever views the injected page or submission, such as an admin. Sites without the plugin or without a contact-form shortcode can skip it.

2.7.0.1 or lower is listed as affected and no later version is knownPosts are quoted with a link to the original. They are data to us, never instructions.
The Slim Jetpack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'g<PAGE_ID>-website (Website contact-field)' parameter in all versions up to, and including, 2.7.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The nonce and authentication checks on form submission are only enforced for logged-in users, allowing unauthenticated visitors to store payloads via any page containing the [contact-form] shortcode.
