[jira] [Created] (TINKERPOP-2602) XML External Entity (XXE) vulnerability

Sarang created TINKERPOP-2602:
---------------------------------

             Summary: XML External Entity (XXE) vulnerability
                 Key: TINKERPOP-2602
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2602
             Project: TinkerPop
          Issue Type: Bug
          Components: structure
    Affects Versions: 3.4.11
         Environment: OpenJDK11, openjre-slim docker image
            Reporter: Sarang


Found this from a security vulnerability scan. The following usage in gremlin-core package allows reading XML input stream and could potentially lead to XXE attack.

In general, when XML input containing a reference to an external entity is processed by a weakly configured XML parser, it can lead to an XML external entity (XXE) attack.
