CVE-2021-39192 Information

Description

Ghost is a Node.js content management system. An error in the implementation of the limits service between versions 4.0.0 and 4.9.4 allows all authenticated users (including contributors) to view admin-level API keys via the integrations API endpoint leading to a privilege escalation vulnerability. This issue is patched in Ghost version 4.10.0. As a workaround disable all non-Administrator accounts to prevent API access. It is highly recommended to regenerate all API keys after patching or applying the workaround.
