The crewjam/saml go library prior to version 0.4.9 is vulnerable to an authentication bypass when processing SAML responses containing multiple Assertion elements. This issue has been corrected in version 0.4.9. There are no workarounds other than upgrading to a fixed version.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
