Vulnerability from cvelistv5 – Published: 2026-08-07 07:25 – Updated: 2026-08-07 15:19

Title

Simple CAPTCHA with Cloudflare Turnstile < 1.42.0 - Unauthenticated Turnstile Protection Bypass via Reusable Forminator Cache Key

Summary

The Simple CAPTCHA with Cloudflare Turnstile WordPress plugin before 1.42.0 does not bind its Turnstile validation cache to the single-use challenge token in its Forminator integration, instead keying it to an attacker-controlled, reusable request value, allowing unauthenticated attackers to solve one challenge and then replay token-less form submissions for a short window, defeating the anti-abuse protection the plugin provides.
