Summary

Red Hat Quay 3 contains a DOM-based cross-site scripting flaw in the signin page, where the redirect_url value is not validated before the browser navigates to it. A remote attacker can trick a user into logging in through a crafted link, so arbitrary script runs in the victim's authenticated browser session. Exploitation requires the Quay deployment to use direct database authentication.

Description from the CNA

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.
