An XML External Entity (XXE) vulnerability exists in the Charles 4.2.7 import/export setup option. If a user imports a Charles Settings.xml file from an attacker, an intranet network may be accessed and information may be leaked.
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.
