CVE-2026-78103

Dimension Log Server Configuration Lock Bypass Vulnerability

Medium 5.1 CVSS v4.0 › Published 2026-08-27Updated 2026-08-27

Summary #

WatchGuard Dimension provides a client-side lock/unlock UI control for management changes. The server-side configuration endpoint does not enforce this lock/unlock workflow state, allowing an authenticated administrator to submit configuration changes directly to the endpoint without first completing the UI unlock step. This allows an authenticated read-write administrator session to bypass the intended editing workflow and overwrite configuration changes being made by another concurrent administrator session.
