What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Ghost (npm package 'ghost') versions from 3.23.0 up to, but not including, 6.23.0 expose API keys to users with low-privilege staff accounts. An authenticated low-privilege staff user can read API keys returned by the Admin API, which are intended to be available only to higher-privileged users.
