Upstream source description

A flaw was found in Red Hat Quay. An administrator of any repository, by knowing or guessing a target notification's Universally Unique Identifier (UUID), can read the notification configuration, including sensitive details like webhook URLs, Slack tokens, and email addresses. This vulnerability also allows them to trigger test notifications for another repository. This could lead to unauthorized information disclosure and potential misuse of notification services.
