CVE-2026-50543

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 authorization on POST /displaygroup/criteria/{displayGroupId} allows an authenticated user to send criteria updates to any display via XMR. These criteria determine schedule changes and can alter playback, for example by causing content scheduled for rainy weather to play when it is not raining. Exploitation requires Schedule Criteria to be in use on the CMS. This issue is fixed in version 4.4.3.
