Summary

OmniAuth-SAML authentication bypass via incorrect XML canonicalization and DOM traversal

Details

OmniAuth OmniAuth-SAML 1.9.0 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.

Severity ?

7.7 (High)
