How to fix?

Upgrade Echo:latest golang-1.19 to version 1.19.3-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-1.19 package and not the golang-1.19 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" sets the variables "A=B" and "C=D".
