Ghost vulnerable to information disclosure of private API fields
### 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`. ### For more information If you have any questions or comments about this advisory: * Email us at [security@ghost.org](mailto:security@ghost.org)
