While firmware updates aim to improve performance and fix bugs, current users of specific versions—particularly v16.03.34.06 and v16.03.33.05—are at high risk of remote exploitation. Critical Security Vulnerabilities (2025–2026)
Several "Critical" rated vulnerabilities have been identified that allow remote attackers to achieve full device compromise:
