Ghost · Ghost · CVE-2023-31133
**Name of the Vulnerable Software and Affected Versions**
Ghost versions prior to 5.46.1
**Description**
The issue is due to a lack of validation when filtering on the public API endpoints, making it possible to reveal private fields via a brute force attack. Ghost(Pro) has already been patched, and there is 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.
**Recommendations**
For Ghost versions prior to 5.46.1, update to version 5.46.1 to resolve the issue.
As a temporary workaround, consider adding a block for requests to "/ghost/api/content/*" where the `filter` query parameter contains `password` or `email`.
