Technical details

The form submission endpoint's verify() method returns early if the g-recaptcha-token field is empty or absent, allowing unauthenticated attackers to bypass reCAPTCHA validation. This results in unbounded form submissions triggering notification emails, webhooks, and writes to the submissions table without proper security verification.
