CVE-2026-79701: 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
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 ajaxcontact, optinform and formbuilder 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 viewtype parameter equalled module. Submitting viewtype=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 viewtype parameter was never validated against the context in which the form was actually rendered.

Event History
Frequently Asked Questions
Which deployments are affected?
Every Contact, Opt-in, or Form Builder addon instance placed inside an SP Page Builder module is affected in versions 3.2.6 through 6.9.0. The configured CAPTCHA type does not change exposure.
What does an attacker need to bypass CAPTCHA verification?
No authentication is required. An attacker can submit the form request with view_type=module and any non-empty arbitrary token value, because the request parameter is not validated against the form's actual rendering context.
