CVE-2026-50543 · Xibo: Missing Authorization on POST /displaygroup/criteria/{displayGroupId} Allows Arbitrary Scheduling Criteria Injection to Player Devices
Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.
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.
