Doc Text:
A flaw was found in Katello where the Docker Tags repositories API does not properly enforce organization scoping when listing repositories for a Docker meta tag. An authenticated user with permission to view products in one organization may be able to retrieve repository metadata associated with Docker tags belonging to another organization by supplying the tag identifier. This can result in unauthorized disclosure of repository configuration information across organization boundaries.

Description OSIDB Bzimport 2026-10-08 03:31:45 UTC
A flaw was found in Katello. The Docker Tags repositories API endpoint resolves a DockerMetaTag with an unscoped find and returns associated repositories without intersecting Repository.readable. An authenticated user with view_products permission in one organization can enumerate repository metadata (names, product associations, content types, upstream URLs) for Docker tags belonging to other organizations by supplying the tag identifier and omitting the optional organization filter. Reported via PSIRTSUPT-25120.
