Simple Captcha With Cloudflare Turnstile
Monthly
CAPTCHA bypass in the Simple CAPTCHA with Cloudflare Turnstile WordPress plugin before 1.42.0 allows unauthenticated network attackers to defeat anti-abuse protections on Forminator-integrated forms by exploiting a flawed validation cache keying mechanism. After solving a single legitimate Turnstile challenge, an attacker can replay token-less form submissions during the validation cache window because the cache is bound to an attacker-controlled, reusable request value rather than the one-time challenge token. A publicly available proof-of-concept exists (WPScan); this vulnerability is not currently listed in CISA KEV, and no EPSS score was provided in source data.
