CVE-2026-13206Network attack vector

Unauthenticated command execution via unneutralized input

Published Aug 10, 2026 · Updated Aug 10, 2026

OS command injection in Zyxel Networks WAH7601 20072026 and earlier allows remote attackers to execute operating system commands. The affected OS-command operation fails to neutralize special input elements, but the published material does not identify its endpoint or parameter. Network access is sufficient without authentication or user interaction, and successful execution can read or alter device data or interrupt service.
