Overview

ruby-saml is a SAML toolkit for Ruby on Rails.

Affected versions of this gem are vulnerable to an XML signature wrapping attack. This occurs in the specific scenario where there was a signature that referenced at the same time 2 elements (but past the scheme validator process since 1 of the element was inside the encrypted assertion).
