Vulnerability from github – Published: 2026-06-23 15:32 – Updated: 2026-06-24 00:30

Details

OpenRemote Manager before 1.24.2 contains an insecure direct object reference vulnerability in the removeAlarms() method that allows authenticated users to delete alarms from other tenants by supplying arbitrary alarm IDs. The bulk deletion endpoint fails to validate that targeted alarm IDs belong to the caller's realm, enabling cross-tenant permanent destruction of safety-critical and security alerts.

CVE-2026-56784 (GCVE-0-2026-56784)

Vulnerability from cvelistv5 – Published: 2026-06-23 12:13 – Updated: 2026-06-23 21:02 X_Open Source

Title

OpenRemote < 1.25.0 IDOR via Bulk Alarm Deletion Endpoint

Summary

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.

Severity

8.6 (High)
