PraisonAI is a multi-agent teams system. Prior to version 4.6.78, the deploy/api.py module generates Python server code by directly interpolating the agents_file parameter into an f-string that is then written to a file and executed via subprocess.Popen(). An attacker who controls the agents_file value (via CLI argument, configuration, or upstream API) can inject arbitrary Python code. Version 4.6.78 patches the issue.
