What is CVE-2026-107444?

A flaw exists in Katello's Docker Tags repositories API that fails to enforce proper organization scoping when authenticating requests to list repositories. This flaw allows an authenticated user, who has the right permissions within one organization, to access repository metadata associated with Docker tags that belong to a different organization by providing the corresponding tag identifier. Such an issue poses risks of unauthorized disclosure of sensitive repository configuration information across organizational boundaries, potentially leading to data breaches and compliance violations.
