Summary
Ghost vulnerable to information disclosure of private API fields
Details

Impact

Due to a lack of validation when filtering on the public API endpoints, it is possible to reveal private fields via a brute force attack.

Ghost(Pro) has already been patched. We can find no evidence that the issue was exploited on Ghost(Pro) prior to the patch being added.

Self-hosters are impacted if running Ghost a version below v5.46.1. Immediate action should be taken to secure your site - see patches and workarounds below.

Patches

v5.46.1 contains a fix for this issue.

Workarounds

Add a block for requests to /ghost/api/content/* where the filter query parameter contains password or email.
