CVE-2023-6963Network attack vector

CAPTCHA bypass via omitted reCAPTCHA response

Published Feb 5, 2024 · Updated Apr 8, 2026

CAPTCHA bypass in Getwid – Gutenberg Blocks 2.0.4 and earlier allows remote attackers to submit Contact Forms without reCAPTCHA. The Contact Form submission handler accepts a data array that omits g-recaptcha-response instead of rejecting the missing token. No authentication is required; reCAPTCHA keys and a Getwid Contact Form must be configured, and successful abuse delivers unwanted form email.
