Summary
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.
Exploit prediction (EPSS)
2.46% probability of exploitation in the next 30 days, higher than 85% of all scored CVEs.
