CVE-2026-78610Network attack vector

Administrator account takeover via passphrase-change CSRF

Published Aug 27, 2026 · Updated Aug 27, 2026

Cross-site request forgery in WatchGuard Dimension 2.0 through 2.3.0 allows remote attackers to change a global administrator's passphrase. The Web UI accepts the state-changing passphrase request from a crafted page without verifying that the administrator intentionally initiated it. Exploitation requires an active global-administrator session and induced browser navigation, enabling attacker-chosen credential replacement and administrator lockout.
