Command injection is anytime you’re calling a process using popen, subprocess, os.system and taking arguments from variables.

You might not even be aware that one of your dependencies leaves itself open to these types of attacks. Well, the standard library modules, etree, DOM, xmlrpc are all wide open to these types of attacks.
