Official Description

OpenRemote before 1.25.0 contains an insecure direct object reference (IDOR) vulnerability in the bulk alarm deletion endpoint that allows authenticated users to permanently delete alarms belonging to other tenants by supplying arbitrary alarm IDs. The removeAlarms() method in AlarmResourceImpl.java omits realm-scoping validation in its JPA query, enabling any user with alarm-write permissions to enumerate sequential auto-increment alarm IDs and delete cross-tenant alarm records without authorization.

Technical Analysis

CVE-2026-56784 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 8.1.
