Important: After installing this firmware, we strongly recommend performing a factory-default reset to activate every new security adjustment.
Security Enhancements
- Password Policy Upgrade – Minimum 10 characters with at least 1 letter, 1 digit and 1 special symbol, and no consecutive identical characters; hardens defense against brute-force attacks.
- HTTPS on 8443 – Management interface now served over TLS by default.
- UPnP Disabled – Universal Plug and Play starts in the off state for reduced surface exposure.
- AiCloud Authentication Hardening (CWE-287) – Added layered verification.
- Authentication Logic Refactor – Removed redundant code paths for a lean sign-in flow.
- Memory Safety Guard (CWE-476) – Introduced null-reference protections across critical services.
- Enhanced IPsec Parameter Validation – The existing input checks have been hardened
- Data Exposure Mitigation (CWE-200) – Reinforced controls on sensitive pathways.
- Detailed Audit Trails – Expanded logging within the authentication module.
System Improvements
- Connection Stability – Core algorithms refined for steadier links.
- Scheduling Accuracy – Timed tasks execute reliably under PPPoE, PPTP and L2TP WAN modes.
- Client List Maintenance – Resolved an issue that prevented offline devices from being removed from the client list.
Bug Fixes:
- Fixed abnormal client list.
- Fixed abnormal GUI behavior of Wireguard VPN.
- Fixed USB internet backup conflict with main WAN.
- Fixed abnormal WAN detection while AiDetection is enabled.
- Improved AdGuard DNS GUI issues.
- Fixed IPv6 related issues.
- Improved USB tether compatibility for pixel phones.
