Supports Surfshark VPN account login for a smoother user experience. (Supported model only)

Fixed an issue that could cause DNS resolution failures and loss of Internet access when DNSSEC is enabled.

Security Fixes
Web management interface: Strengthened data handling for the connected device list and added stricter content checks when importing configuration profiles.
Network speed test service: Added allowlist validation for service command parameters, so that only expected values are accepted.
System protection service: Adjusted address parameter validation and event logging, strengthening access control between local services.
Certificate import process: Adjusted file handling and password passing, with stricter parameter validation.
Third-party account authorization: Narrowed the recipients of authorization data to better protect authorization information.
Web management interface: Adjusted the output handling of feedback content.
Notification service: Added identity verification for local connection sources and tightened the related file permission settings.
Mobile device connection authorization: Added a device matching check to strengthen the access token issuance process.
Device discovery service: Removed a non-essential internal function endpoint to strengthen overall access control.
AiMesh: Adjusted data access protection during the node joining process, improving system stability while connections are being established.
System temporary directory: Adjusted the default permissions applied at creation time to narrow local file access.
Network diagnostic data query: Strengthened value range checks for time interval parameters.
Network diagnostic data query: Added allowlist validation for query fields.
Internal data query: Improved field matching logic and optimized the memory release process under error conditions.
Time synchronization settings: Strengthened parameter validation for the server name.
File upload handling: Fixed an issue where certain input formats could cause the web management service to become unresponsive.
Wireless channel selection tool: Adjusted the handling of command parameters to prevent unintended command execution.
Certificate upload: Added a pre-check of archive contents to prevent files from being written to unintended locations.
System configuration file generation: Strengthened parameter content checks to prevent abnormal configuration values from affecting network service settings.
VPN and account authentication services: Adjusted the handling of connection settings and account data, with stricter parameter validation.

We recommend updating to this version to maintain optimal protection.
