Overview
devise is a flexible authentication solution for Rails with Warden.
Affected versions of this package are vulnerable to Open Redirect in the FailureApp#redirect_url method when handling non-GET requests after a session timeout. An attacker can cause users to be redirected to arbitrary external URLs by crafting a page with an auto-submitting cross-origin form or by enticing victims to click malicious links, potentially leading to phishing or credential theft.
