The TransformerFactory in Apache Xalan-Java before 2.7.2 does not properly restrict access to certain properties when FEATURE_SECURE_PROCESSING is enabled, which allows remote attackers to bypass expected restrictions and load arbitrary classes or access external resources via a crafted (1) xalan:content-header, (2) xalan:entities, (3) xslt:content-header, or (4) xslt:entities property, or a Java property that is bound to the XSLT 1.0 system-property function.
