info:
  name: Journyx - XML External Entities Injection (XXE)
  author: s4e-io
  severity: high
  description: |
    The "soap_cgi.pyc" API handler allows the XML body of SOAP requests to contain references to external entities. This allows an unauthenticated attacker to read local files, perform server-side request forgery, and overwhelm the web server resources.
