CVE-2026-15239

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

Description (CNA)

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.
