Upgrade ghost to version 6.54.1 or higher.
Overview
ghost is a publishing platform
Affected versions of this package are vulnerable to Information Exposure via the posts and pages browse and export filtering paths in PostsService, PostsExporter, and the posts/pages admin controllers. An attacker can leak other staff users’ password hashes by sending an admin API request with a crafted filter such as authors.password:abcd on /posts, /posts/export, or /pages.
Notes
- The leak only applies to staff-admin requests that use the admin API browse/export filter syntax on posts or pages; the maintainer advisory says the hashes were exposed to any staff-level user.
Workarounds
- Enable Multi-factor Authentication (MFA) for all staff users to reduce the chance that a recovered password hash can be used to log in and take over an account.
