USB is insecure. There are USB sticks that will destroy your computer, USB sticks loaded with spyware, and even official enterprise USB sticks infected with malware. Windows and Macs are easy to crack with USB-borne tools.

There are devices like the USG USB stick firewall, which can protect you.

Linux users can stop attackers armed with USB sticks with USBGuard software. It is not well known. It should be. You can install USBGuard on any Linux.
