CVE-2026-33390Network attack vector

Authenticated configuration tampering via sensor synchronization

Published Jul 9, 2026 · Updated Jul 9, 2026

Incorrect privilege assignment in Nozomi Networks Guardian and CMC before 26.2.0 allows remote authenticated users to alter configuration. The synchronization path grants Arc sensors CLI permissions and accepts their relayed commands with administrative authority. Limited product access and an enabled sensor are required; successful commands can change device settings or interrupt service.
