## Technical details

The vulnerability is an XML External Entity (XXE) injection (CWE-611) within Hitachi Vantara Pentaho Data Integration & Analytics. The root cause is the failure of certain XML parsers within the application to properly restrict or disable the resolution of external entities when processing XML-based input. An authenticated attacker with network access can exploit this by submitting a specially crafted XML document. Successful exploitation allows the attacker to read local files from the server filesystem or perform Server-Side Request Forgery (SSRF) to interact with internal services. The issue is resolved in versions 10.2.0.7 and 11.0.0.0.
