CVE-2022-31040Network attack vector

Phishing redirects via unvalidated referer parameter

Published Jun 13, 2022 · Updated Apr 23, 2025

Open redirect in the cookie consent page in Open Forms before 1.0.9 and 1.1.0-rc0 through 1.1.0 allows remote attackers to redirect users. The cookiegroup_list template copies a crafted referer query parameter into its Close link and consent-form next value without validating the destination host or scheme. A user must open the crafted page and activate a consent control, after which the trusted application sends the browser to an attacker-controlled phishing site.
