Security Fixes
- Enhanced input validation and protection to reduce the risk of command injection and SQL injection.
- Hardened environment variable handling.
- Hardened protections around specific logging/command composition flows to reduce potential injection risks.
- Patched a command injection risk in a specific network diagnostic function.

We recommend upgrading to this version to maintain best protection.

Please unzip the firmware file, and then verify the checksum.

It is also called RT-AX54HP V2 or RT-AX1800HP V2 in other regions so go check their respective websites (they use the same firmware). RT-AX57M / RT-AX3000S uses identical hardware and has the same firmware update (same hash) as well, but with 160MHz unlocked on 5GHz.
