发现 Katello 中存在一个漏洞：Docker Tags 仓库 API 在列出与 Docker 元标签关联的仓库时，未能正确强制执行组织范围的隔离。具有查看某一组织中产品权限的已认证用户，可以通过提供标签标识符，检索到属于其他组织的 Docker 标签所关联的仓库元数据。这可能导致跨组织边界未经授权地泄露仓库配置信息。

Vulnerability Description
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.
