How to fix?

Upgrade Debian:9 mercurial to version 4.0-1+deb9u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mercurial package and not the mercurial package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks.
