CVE-2021-33813: XML External Entity (XXE) Injection in JDOM
(updated )
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.
