CVE-2017-11430: Multiple SAML libraries may allow authentication bypass via incorrect XML canonicalization and DOM traversal
First published: Wed Apr 17 2019(Updated: )
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.
