Details

As written in the advisory (Markdown source, shown as plain text).

An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to cause a denial of service via a crafted HTTP request. As a workaround, to avoid external entities being expanded, one can call `builder.setExpandEntities(false)` and they won't be expanded.
