## From the sources

Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.3, missing access-control checks on `GET /layout/status/{id}` allow an authenticated user with any privileges to view the `status and metadata` of any layout, including layouts for which the user does not have view rights. This issue is fixed in version 4.4.3.
