Restlet Framework before 2.3.12 allows remote attackers to access arbitrary files via a crafted REST API HTTP request that conducts an XXE attack, because only general external entities (not parameter external entities) are properly considered. This is related to XmlRepresentation, DOMRepresentation, SaxRepresentation, and JacksonRepresentation.
Weakness
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
