# LeadSnap WordPress plugin: unauthenticated PHP object injection in versions up to 1.25

LeadSnap, a plugin for WordPress sites, deserializes attacker-supplied PHP objects without authentication. A remote visitor may be able to trigger object injection, which can lead to code execution on the server.

## How to check

- Check whether the LeadSnap plugin is installed on your WordPress sites and note its version.

## Fix

- LeadSnap: move to a version later than `1.25`; the sources do not name the fixed version.
