CVE-2026-107444: Katello Docker Tags API organization scope bypass

CVE-2026-107444 · Severity: medium · CVSS 4.3 · Published 2026-10-08

Katello, a repository and content management component in Red Hat Satellite, fails to properly restrict Docker tag repository access by organization. An authenticated user with permission to view products in one organization can retrieve repository metadata from other organizations, exposing repository names, product associations, and configuration details they should not have access to.

Technologies: Red Hat Satellite. Vendors: Red Hat.

Technical details

The Docker Tags repositories API endpoint performs an unscoped lookup of Docker meta tags and returns associated repositories without enforcing organization boundaries or access control checks. An authenticated user can supply a Docker tag identifier from another organization and omit the optional organization filter to enumerate repository configuration data across organization boundaries. The flaw affects confidentiality only; no integrity or availability impact.
