NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby-saml package and not the ruby-saml package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

OneLogin Ruby-SAML 1.6.0 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.
