SP Page Builder Pro vulnerabilities

In the Dynamic Content Filter addon in SP Page Builder Pro versions 3.0.0–5.6.1p2, there is reflected XSS. The slider minimum and maximum values are taken from the dc_filter_<fieldId> parameter, split on "l-r", HTML-escaped inside the data-value attribute, and then echoed without escaping as the span element's text content.

Joomla extension SP Page Builder Pro contains a vulnerability that allows bypassing CAPTCHA in Contact, Opt-in and Form Builder addons. An attacker can send a request with view_type=module and any token, causing CAPTCHA verification to be skipped.

In the SP Page Builder Pro extension (versions 5.1.4 - 6.9.0), the optin_form addon read the CAPTCHA type, expected answer, and 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, allowing unauthenticated CAPTCHA bypass.
