    Title
    Multiple SAML libraries may allow authentication bypass via incorrect XML canonicalization and DOM traversal
    Summary
    OneLogin PythonSAML 2.3.0 and earlier may incorrectly utilize the results of 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, allowing the attack to potentially bypass authentication to SAML service providers.
