## Overview

A flaw was found in Quay. A remote attacker could trick a user into logging in through a crafted link, resulting in cross-site scripting (XSS). Because the application does not validate the redirect destination before navigating, this flaw allows the execution of arbitrary script in the context of the victim's authenticated browser session. Successful exploitation requires the target Quay deployment to use direct database authentication and the victim to complete login through the malicious URL.
