What is CVE-2026-56120?

The version of OpenRemote prior to 1.25.0 contains an insecure direct object reference vulnerability within the bulk alarm deletion functionality. Authenticated users can exploit this flaw to permanently delete alarms belonging to other tenants by providing arbitrary alarm IDs. The key issue arises from the removeAlarms() method, which fails to apply proper realm-scoping validation, allowing users with alarm-write permissions to iterate over sequential auto-incremented alarm IDs and delete alarms without proper authorization checks.
