Directory Traversal

Overview datamodel-code-generator is a Datamodel Code Generator Affected versions of this package are vulnerable to Directory Traversal via the schemaLocation attribute in XSD processing. An attacker can access arbitrary files on the local filesystem by supplying a crafted XML Schema file that us...
