Trivys eigenes Label ist CRITICAL. Kritisch laut NVD, Ruby Advisory DB. Niedriger laut GHSA (hoch).
Beschreibung
OmniAuth OmnitAuth-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.
