Vulnerability Overview

CWE-601: URL Redirection to Untrusted Site ('Open Redirect')

Integration for HubSpot and Contact Form 7, WPForms, Elementor, Ninja Forms <= 1.2.8 carries this weakness at state, and reaching it takes a caller who can reach the endpoint. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.

A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For Integration for HubSpot and Contact Form 7, WPForms, Elementor, Ninja Forms the fix is 1.2.9: builds <= 1.2.8 are affected, anything from 1.2.9 onward is not.
