## Overview

PyTorch Lightning version 1.5.10 and prior is vulnerable to code injection. An attacker could execute commands on the target OS running the operating system by setting the `PL_TRAINER_GPUS` when using the `Trainer` module. A [patch](https://github.com/pytorchlightning/pytorch-lightning/commit/8b7a12c52e52a06408e9231647839ddb4665e8ae) is included in the `1.6.0` release.

## Affected packages

- `pytorch-lightning < 1.6.0`

## Remediation

Upgrade to a patched release:

- `pytorch-lightning 1.6.0`
