Overview

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature where Wizkunde SAMLBase can incorrectly utilize the results of the XML DOM traversal and canonicalization APIs in such a way that an attacker may be able to manipulate the SAML data without invalidating the cryptographic signature. This allows the attack to potentially bypass authentication to SAML service providers.
