Summary

A flaw was found in Red Hat Quay. When Red Hat Quay requests password re-verification for sensitive operations, such as token generation or robot account creation, the re-authentication prompt can be bypassed. This allows a user with a timed-out session, or an attacker with access to an idle authenticated browser session, to perform privileged actions without providing valid credentials. The vulnerability enables unauthorized execution of sensitive operations despite the user interface displaying an error for invalid credentials.
