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."}],"source":{"advisory":"GHSA-737f-mfxg-jv9q","discovery":"UNKNOWN"}}}}
