# PoC: wandb Launch Command Injection (CWE-78)

## Vulnerability

The wandb Python SDK (v0.24.2) Launch feature constructs Docker commands where
`entry_cmd` and `additional_args` are NOT shell-quoted, but the result is passed
to `bash -c` for execution. Shell metacharacters enable command injection.

## Affected Code

| # | File | Line | Issue |
|---|------|------|-------|
| 1 | `local_container.py` | 290 | `entry_cmd[0]` not quoted |
| 2 | `local_container.py` | 293 | `entry_cmd[1:]` not quoted |
| 3 | `local_container.py` | 295 | `additional_args` not quoted |
| 4 | `local_process.py` | 69 | `entry_point.command` not quoted |

Inconsistency: env_vars and docker_args ARE properly quoted with shlex.quote().

## Running the PoC

```bash
pip install wandb
python3 poc_wandb_cmd_injection.py
```
