How to fix?

Upgrade org.apache.santuario:xmlsec to version 1.4.8, 1.5.5 or higher.


org.apache.santuario:xmlsec is a package to provide implementation of the primary security standards for XML, XML-Signature Syntax and Processing and XML Encryption Syntax and Processing.

Affected versions of this package are vulnerable to XML signature spoofing. The class DOMCanonicalizationMethod within jcp/xml/dsig/internal/dom/DOMCanonicalizationMethod.java allows context-dependent attackers to spoof an XML Signature by using the CanonicalizationMethod parameter to specify an arbitrary weak "canonicalization algorithm to apply to the SignedInfo part of the Signature."
