CVE-2026-66013 · Severity: info · CVSS 9.3 · Published 2026-07-25

OpenRemote, an open-source IoT platform, contains a security flaw in how it handles mobile and web console registrations. An attacker who knows a specific console's ID can remotely modify its settings without a password. This allows unauthorized parties to hijack push notifications, potentially intercepting sensitive alerts or preventing legitimate users from receiving critical system updates.

## Technical details

An authentication bypass exists in the OpenRemote console registration API due to an Insecure Direct Object Reference (IDOR) flaw (CWE-639). The endpoint, intended for anonymous registration of new consoles, fails to validate ownership or require authentication when a request provides an ID belonging to an existing console asset. By sending a crafted POST request to /api/console/register with a known asset ID, an unauthenticated attacker can overwrite console provider data and metadata. This enables the replacement of push notification tokens (FCM/APNs), allowing the redirection of sensitive notification traffic to an attacker-controlled device or causing a denial of service for legitimate notifications. The vulnerability is patched in version 1.26.2.
