CVE-2026-79700 Details
Description
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. Verification reduced to md5($captcha_question) != $captcha_answer with both operands supplied by the attacker, so any value passed.
A vulnerability exists in the SP Page Builder Pro extension for Joomla, specifically in versions 5.1.4 through 6.9.0. The issue allows for an unauthenticated bypass of CAPTCHA protections in the optin_form addon. This is achieved by manipulating the CAPTCHA type, expected answer, and enabled flag through the request, instead of using the addon’s stored configuration. The CAPTCHA verification process is compromised, as it only compares an MD5 hash of the CAPTCHA question to the answer, with both values supplied by the attacker, allowing any value to be accepted.
