How to fix?

Upgrade ActiveRecord to versions 2.3.17, 2.4, 3.2 or higher.


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.

Affected versions of this package are vulnerable to Access Restriction Bypass via the attr_protected method of the Active Record. The issue is triggered during the handling of a specially crafted request, which may allow a remote attacker to bypass protection mechanisms and alter values that would otherwise be protected.
