CVE-2026-13086 is a stack-based buffer overflow in the Endpoint Protection Manager (epm) service used by the deprecated Mobile Security feature in WatchGuard Fireware OS. The service can be reached by an unauthenticated remote attacker using specially crafted network traffic, resulting in arbitrary code execution. The epm service has been reported to run as root and to lack stack-canary and PIE protections, increasing the potential consequence of successful exploitation.
