Summary
### Impact
The attack allows extracting sensitive properties of database objects that are associated with users or entries belonging to an account that the attacker has access to.
Pageflow uses the `ActiveAdmin` Ruby library to provide some management features to its users. `ActiveAdmin` relies on the `Ransack` library to implement search functionality. In its default configuration, `Ransack` will allow for query conditions based on properties of associated database objects [1]. The `*_starts_with`, `*_ends_with` or `*_contains` search matchers [2] can then be abused to exfiltrate sensitive string values of associated database objects via character-by-character brute-force.

### Mitigation
Upgrade to version 15.7.1 or 14.5.2 of the `pageflow` gem.
