CVE-2026-49439: OpenRemote missing authorization for predicted datapoint writes

CVE-2026-49439 · Severity: medium · CVSS 4.3 · Published 2026-09-11

OpenRemote is an open-source IoT device management platform. A security flaw allows users who should only have permission to view data to actually modify 'predicted datapoints' for assets. This could allow an unauthorized user to tamper with forecasting data or system projections, potentially leading to incorrect automated decisions or misleading reports.

Technologies: io.openremote:openremote-manager (Maven). Vendors: Maven.

Technical details

A missing authorization check (CWE-862) exists in the OpenRemote Manager's predicted datapoint write endpoint. The endpoint `PUT /api/{realm}/asset/predicted/{assetId}/{attributeName}` incorrectly validates for `READ_ASSETS` privileges instead of requiring `WRITE_ASSETS`. An authenticated attacker with low-level read permissions can exploit this by sending a crafted PUT request to modify asset attributes. This issue is resolved in version 1.24.1.
