CVE-2024-31341Network attack vector

Unauthenticated registration via email-domain restriction bypass

Published May 17, 2024 · Updated Apr 28, 2026

Restricted email-domain bypass in Cozmoslabs Profile Builder 3.11.2 and earlier allows remote attackers to register forbidden addresses. The registration path accepts an email barred by the configured allow/deny domains option because the plugin does not verify that restriction correctly. Exploitation requires exposed Profile Builder registration and configured domain restrictions; the bounded result is an account using a prohibited email domain.
