OpenRemote versions before 1.26.2 contain an information disclosure vulnerability in the SyslogResource REST endpoint that fails to filter operational logs by realm. Attackers with the read:rules role can access the GET /api/{realm}/syslog/event endpoint to retrieve operational logs from all tenants, exposing asset IDs, agent connection details, rule names, and protocol errors across the multi-tenant deployment.
