CVE-2026-50541

medium

Description

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 /dataset/export/csv/{id}` allow an authenticated user to export data from any dataset, including datasets created by administrators, by iterating over `sequential dataset IDs`. Exploitation requires access to the privilege allowing edits, including deletion, to all created `DataSets` independently of Layouts. This privilege is not granted to non-administrators as standard. This issue is fixed in version 4.4.3.
