# Legal Stone WordPress plugin: unauthenticated PHP object injection before 1.2.12

Legal Stone, a WordPress plugin, versions up to and including 1.2.11 accept untrusted serialized PHP data without authentication. A remote attacker can use PHP object injection to potentially run code or take control of the site.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Legal Stone plugin version in the WordPress admin under Plugins, or with `wp plugin get legal-stone --field=version` if WP-CLI is available.
- Treat any version at or below `1.2.11` as exposed.

## Fix

- Legal Stone: unknown; sources give no fixed version beyond the affected range ending at `1.2.11`.
