leshan-core is vulnerable to XML External Entity (XXE) Injection. The vulnerability exists because the DDFFileParser function of DDFFileParser.java and the validate function of DefaultDDFFileValidator.java does not properly sanitize external DTDs by default, which allows an attacker to inject and execute maliciously crafted XML documents. This vulnerability is only applicable in an application that parses (untrusted) DDF model files.
