MaxKB is an open-source AI assistant for enterprise. Prior to version 2.0.0, the sandbox design rules can be bypassed be

MaxKB is an open-source AI assistant for enterprise. Prior to version 2.0.0, the sandbox design rules can be bypassed because MaxKB only restricts the execution permissions of files in a specific directory. Therefore, an attacker can use the shutil.copy2 method in Python to copy the command they want to execute to the executable directory.

This bypasses directory restrictions and reverse shell. Version 2.0.0 fixes the issue.
