Description
OpenRemote versions before 1.28.0 contain a cross-realm information disclosure vulnerability in the Notification REST API that allows per-realm tenant administrators to read all tenants- sent notifications including message bodies. Attackers with read:admin credentials in one realm can submit a zero-parameter GET request to the notification endpoint to retrieve sensitive notification metadata and message content from all realms.
