CVE-2026-65009 · Severity: medium · CVSS 4.3 · Published 2026-07-21

OpenRemote, an open-source IoT platform, contains a security flaw in how it handles system logs in multi-tenant environments. An authorized user belonging to one organization can view the internal operational logs of all other organizations using the same system. This could allow an attacker to see sensitive technical details such as asset IDs, connection settings, and business rule names belonging to other customers.

## Technical details

An information disclosure vulnerability exists in the SyslogResource REST endpoint (GET /api/{realm}/syslog/event) due to a lack of tenant isolation. The underlying SyslogService.getEvents() method builds a JPA query that filters by time and category but lacks a 'realm' filter, and the SyslogEvent entity itself lacks a realm column. Furthermore, the endpoint incorrectly requires only the 'read:rules' role rather than the stricter 'read:logs' role. A remote authenticated attacker with low privileges can exploit this to retrieve operational logs from all tenants, exposing asset IDs, agent connection details, and business logic across the multi-tenant deployment. The issue is addressed in version 1.26.2.
