Summary

A flaw was found in Katello where the Content View Filter Rules API does not properly enforce authorization on the parent Content View Filter. An authenticated, low-privileged user with Content View permissions in one organization may be able to access and modify filter rules belonging to a Content View Filter in another organization by supplying that filter's identifier. This can result in unauthorized disclosure of filter-rule information and unauthorized changes to unpublished Content View filter configuration.
