Vulnerability in Themeum Kirki
CVE-2026-112348
Kirki plugin for WordPress before 6.2.5 contains a reCAPTCHA bypass vulnerability that allows unauthenticated attackers to submit frontend forms without valid verification by omitting the g-recaptcha-token field from POST requests to the form submission endpoint. Attackers can exploit the verify() method's early return on empty token values to submit unlimited forms, triggering notification emails, webhooks, and unbounded writes to the submissions table without completing reCAPTCHA validation.
