What is CVE-2026-33390?

An Incorrect Privilege Assignment vulnerability has been identified in the synchronization functionality of Nozomi Networks' Arc Sensors. This issue arises because the Arc sensors improperly manage CLI permissions, which allows an authenticated user with limited access rights to execute administrative CLI commands through the sync process.
