Keycloak - SAML Core Package Signature Validation Flaw

A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Referen...

CVE-2026-85393

A flaw was found in node-forge. This vulnerability allows a remote attacker to forge valid RSA PKCS1 v1.5 signatures for arbitrary messages. The flaw occurs because the software fails to properly validate the element count in nested DigestAlgorithm sequences during signature verification. By...
