Subject: CVE-2021-40690: Apache Santuario: Bypass of the secureValidation property
Description:
All versions of Apache Santuario - XML Security for Java prior to
2.2.3 and 2.1.7 are vulnerable to an issue where the
"secureValidation" property is not passed correctly when creating a
KeyInfo from a KeyInfoReference element. This allows an attacker to
abuse an XPath Transform to extract any local .xml files in a
RetrievalMethod element.
