Concurrent configuration overwrite via unenforced editing lock
Published Aug 27, 2026 · Updated Aug 27, 2026
Workflow bypass in WatchGuard Dimension 2.0 through 2.3.0 allows remote authenticated users to overwrite concurrent configuration changes. The server-side configuration endpoint accepts changes without verifying that the submitting session completed the client-side lock and unlock sequence. Exploitation requires a read-write administrator session and another administrator making changes concurrently; the bounded consequence is unauthorized replacement of those changes.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
