## Overview

The `github_workflows` module constructs local directory paths from user-controlled repository names without validating for symlinks. A local attacker sharing the scan directory can plant a symlink at the predictable output path, causing workflow data to be written to an attacker-chosen location.

## Affected packages

- `bbot >= 2.0.0, <= 2.8.4`

## Remediation

Upgrade to a patched release:

- `bbot 2.8.5`
