Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE). The CreatePlace REST endpoint accepts an sppClassName parameter which is used to load an arbitrary class. This class is later instantiated using a constructor with the following signature: <constructor>(String, String, String). An attacker may find a gadget (class) in the application classpath that could be used to achieve Remote Code Execution (RCE) or disrupt the application.
