CVE-2026-78174 is an authenticated privilege-escalation and account-takeover vulnerability in WatchGuard Dimension web UI diagnostic logging. Diagnostic logs record unredacted session identifiers for authenticated users. A low-privileged Dimension Administrator who can retrieve these logs can extract the active session token, and associated CSRF token, of a concurrently logged-in Super Administrator and reuse it to impersonate that account. The issue is also associated with exposure of sensitive information (CWE-200) and improper privilege management (CWE-269).
