External redirection via unvalidated returnUrl parameter

Published May 8, 2026 · Updated May 8, 2026

Open redirection in PCommerce E-handel AB Cradle eCommerce's latest demo version allows remote attackers to redirect users externally. The login form endpoint accepts the returnUrl parameter as a redirect destination without validating that the supplied URL remains on the trusted site. Exploitation requires a victim to follow a crafted trusted-domain link, after which the application directs the browser to an attacker-chosen external page.
