Improper Restriction of XML External Entity Reference
Hitachi Vantara Pentaho Business Analytics Server versions before 220.127.116.11 and 18.104.22.168, including 8.3.x do not correctly protect the Post Analysis service endpoint of the data access plugin against out-of-band XML External Entity Reference.
CWE-611 - Improper Restriction of XML External Entity Reference
