How to fix?

There is no fixed version for gogs.io/gogs/internal/ssh.

Overview

gogs.io/gogs/internal/ssh is a painless self-hosted Git service

Affected versions of this package are vulnerable to Arbitrary Argument Injection via the --split-string env argument, which is handled by internal/ssh/ssh.go when the built-in SSH server is enabled. A user with a valid SSH private key can cause arbitrary code to be executed on the server.

Note: Only applications that use the env binary are vulnerable, which is not included in the Windows distribution or the default BusyBox distribution.
