Joomla Extension - joomshaper.com - Unauthenticated CAPTCHA Bypass via Request-Controlled CAPTCHA Configuration in SP Page Builder Pro 5.1.4 - 6.9.0 - The optin_form addon read the CAPTCHA type, the expected answer and the enabled flag from the request rather than from the stored addon configuration.
