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.
