Overview

ActiveRecord is the Object-Relational Mapping (ORM) that comes out-of-the-box with Rails. It plays the role of Model in the MVC architecture employed by Rails.

There's a flaw in the serialize helper in the ActiveRecord. The issue is triggered when the system is configured to allow users to directly provide values to be serialized and deserialized using YAML. With a specially crafted YAML attribute, a remote attacker can deserialize arbitrary YAML and execute code associated with it.
