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.

Affected: PyPI: PraisonAI

### Summary 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.

### Details

`src/praisonai/praisonai/deploy/api.py` (line 80):

```python code = f'''... praisonai = PraisonAI(agent_file="{agents_file}") ... "agent_file": "{agents_file}" ...''' ```

The generated code is then executed (line 190): ```python subprocess.Popen(['python', server_file]) ```

`agents_file` is never sanitized or validated. A malicious value breaks out of the string context:

```python agents_file = '"); import os; os.system("id"); #' # Generated code becomes: # praisonai = PraisonAI(agent_file=""); import os; os.system("id"); #") ```

The same pattern exists in `deploy/docker.py` (line 33) for Dockerfile generation.

### PoC

```python # The injection: agents_file = '"); import os; os.system("id"); #'

# What the generated code looks like: template = f'praisonai = PraisonAI(agent_file="{agents_file}")' print(template) # Output: praisonai = PraisonAI(agent_file=""); import os; os.system("id"); #") ```

### Impact - **Arbitrary code execution** on the machine running the deploy command - **Supply chain risk** if `agents_file` comes from a configuration file or CI/CD pipeline
