CVE-2026-86102Network attack vector

Remote command execution via internal API injection

Published Sep 28, 2026 · Updated Sep 28, 2026

OS command injection in WatchGuard AP firmware before 3.4.8 allows remote attackers to execute shell commands through an internal API service. The internal API service executes operating-system commands from untrusted network input, but the affected endpoint, parameter, and command construction have not been disclosed. Exploitation requires network reachability to the AP; the available advisory text does not establish whether authentication is required.
