How to fix?

Upgrade Alpine:3.13 openssh to version 7.9_p1-r3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Alpine. See How to fix? for Alpine:3.13 relevant fixed versions and status.

In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.
