# External XML Entity Injection (XXE)
## Description
It is possible to cause the application's XML parser to include external resources.
This can include files or in some circumstances initiate requests to third party
servers.
## Remediation
Consult the documentation for the XML Parser used by the target application for security
guidelines and hardening steps. It is recommended that all XML parsers disable external
entity resolution and XML `xinclude` features. Most XML parsers based on `libxml` can also be
configured to disable network access.
