CVE-2026-78495Network attack vector

Adjacent service enumeration via backup connection test

Published Aug 27, 2026 · Updated Aug 27, 2026

SSRF in WatchGuard Dimension 2.0 through 2.3.0 allows remote authenticated users to enumerate adjacent network services. The Remote Backup Connection Test accepts a configured host and port and makes Dimension initiate an SFTP connection without restricting the destination. Privileged access to the system configuration is required, and the observable connection result discloses service exposure rather than service data.
