OpenRemote notification deletion endpoints fail to enforce realm boundaries, allowing any realm administrator to delete notifications belonging to… (CVE-2026-73616)
OpenRemote contains a vulnerability in its notification deletion endpoints where realm boundaries are not enforced. This flaw allows any realm administrator with write:admin privileges in one realm to delete notifications belonging to other realms, including the master realm or other tenants. The vulnerability does not affect confidentiality or availability but impacts integrity by enabling unauthorized deletion of notifications.
AI Analysis
Technical Summary
The OpenRemote notification deletion endpoints fail to enforce realm boundaries, permitting attackers with write:admin role in one realm to send DELETE requests that remove notifications from other realms without proper authorization checks. This vulnerability is identified as CWE-639 (Authorization Bypass Through User-Controlled Key) and has a CVSS 3.1 base score of 6.5, indicating a high severity level. The attack vector is network-based with low attack complexity and requires privileges (write:admin) in at least one realm. There is no indication of known exploits in the wild or available patches at this time.
Potential Impact
An attacker with write:admin privileges in one realm can delete notifications from other realms, including the master realm or other tenants, thereby compromising data integrity related to notifications. There is no impact on confidentiality or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict write:admin privileges carefully and monitor administrative actions related to notification deletions to detect potential abuse.
