Vulnerabilidades do Joomshaper.com SP Page Builder (Pro) extension for Joomla

Joomla Extension - joomshaper.com - Reflected XSS in the Dynamic Content Filter addon in SP Page Builder Pro 3.0.0 - 5.6.1p2 - The slider minimum and maximum values are taken from the dc_filter_<fieldId> request parameter, split on the delimiter "l-r", HTML-escaped inside the data-value attribute, and then echoed without escaping as the span element's text content. An unauthenticated attacker reflects arbitrary HTML or JavaScript into the rendered page through a crafted dc_filter_<fieldId> value.

Joomla Extension - joomshaper.com - Unauthenticated CAPTCHA Bypass in Module Context in the Contact, Opt-in and Form Builder Addons in SP Page Builder Pro 3.2.6 - 5.6.1p2 and 6.0.0 - 6.9.0 - In the ajax_contact, optin_form and form_builder addons, the result returned by the CAPTCHA plugin's onCheckAnswer event was discarded and replaced with a test for a non-empty string whenever the request-supplied view_type parameter equalled module. Submitting view_type=module together with any arbitrary token value therefore passed verification. This affected every instance of these addons placed inside an SP Page Builder module, irrespective of the CAPTCHA type configured for the site, and the view_type parameter was never validated against the context in which the form was actually rendered.

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.
