Beta 2 for docx4j 3.2.2 is now available, from http://www.docx4java.org/docx4j/docx4j-3.2.2-beta2.jar
This beta introduces protection against XML Enternal Entity Injection attacks for some additional cases. (The main cases were addressed in v3.2.0)
Please test to ensure there are no unanticipated side effects which affect your use case.
In the absence of any significant reported issues, docx4j 3.2.2 will be released next week.
