 "title": "Simple CAPTCHA with Cloudflare Turnstile <= 1.44.0 - Unauthenticated CAPTCHA Bypass via Contact Form 7 Turnstile Form-Tag",
 "description": "The Simple CAPTCHA with Cloudflare Turnstile plugin for WordPress is vulnerable to CAPTCHA Bypass via the Contact Form 7 Turnstile form-tag integration in all versions up to, and including, 1.44.0. This is due to the plugin deciding whether a submitted form uses the Turnstile form-tag from the user-supplied '_wpcf7' POST field, instead of from the form Contact Form 7 is actually processing. This makes it possible for unauthenticated attackers to submit Contact Form 7 forms protected with the form-tag without solving Turnstile, by leaving out that field or pointing it at another form. Sites using the 'Enable on all CF7 Forms' option are not affected.",
