Line 184 in cdb8ce9

result = eval(command)

fix the issue need to eliminate the use of eval and replace it with a safer alternative. Instead of dynamically evaluating arbitrary code, we can implement a controlled execution environment where only predefined commands are allowed. This can be achieved by using a dictionary or a similar structure to map command strings to corresponding functions.

Steps to fix:

1. Define a dictionary of allowed commands and their corresponding functions.
2. Replace the eval call with a lookup in the dictionary, followed by a function call.
3. Validate the command input to ensure it matches one of the allowed commands.
4. Update the _execute_command function to use this safer approach.
