Who should care

Defenders managing OpenRemote instances should assess exposure and prioritize remediation to prevent potential unauthorized predicted datapoint writes. They must verify OpenRemote version and privileges, restrict 'read:assets' privileges to prevent unauthorized writes, and monitor predicted datapoint writes for suspicious activity. Security teams and vulnerability management teams should also review and update their

Why it matters

CVE-2026-49439 allows unauthorized predicted datapoint writes in OpenRemote instances before version 1.24.1, requiring defenders to verify and remediate.

  • Potential unauthorized predicted datapoint writes
  • Required verification of OpenRemote version and privileges
  • Need for monitoring predicted datapoint writes

Technical summary

OpenRemote predicted datapoint write endpoint allows users with 'read:assets' privileges to write predicted datapoints before version 1.24.1 due to inadequate access controls, allowing potential unauthorized modifications. Defenders should prioritize verifying and remediating OpenRemote instances to prevent unauthorized predicted datapoint writes. The issue is fixed in version 1.24.1.

Defensive priority

Defenders should prioritize verifying and remediating OpenRemote instances to prevent unauthorized predicted datapoint writes.

Recommended defensive actions

  • Verify OpenRemote version and upgrade to 1.24.1 or later if necessary
  • Restrict 'read:assets' privileges to prevent unauthorized writes
  • Monitor predicted datapoint writes for suspicious activity

Evidence notes

Evidence from OpenRemote and NVD indicates a predicted datapoint write endpoint issue in OpenRemote versions before 1.24.1, allowing users with 'read:assets' privileges to write predicted datapoints.
