## Overview

The `postman_download` module uses the workspace `name` field from the Postman API to construct the local directory path without sanitization. If a malicious workspace has a name containing path traversal characters, pathlib resolves the path outside the intended output directory, allowing an attacker to write arbitrary files to the user's system.

## Affected packages

- `bbot >= 2.1.0, <= 2.8.5`

## Remediation

Upgrade to a patched release:

- `bbot 2.8.6`
