# Avventure WordPress plugin: unauthenticated PHP object injection through 1.1.12

The Avventure plugin for WordPress, versions up to and including 1.1.12, deserializes attacker-supplied PHP objects without authentication. An attacker who can send a crafted request may be able to run code on the server or read data.

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

## How to check

- Check the installed Avventure plugin version in the WordPress admin plugin list or the `avventure` plugin header.

## Fix
