## Affected

- some-natalie ghas-to-csv: fixed in v1

## Description

some-natalie/ghas-to-csv (GitHub Advanced Security to CSV) is a GitHub action which scrapes the GitHub Advanced Security API and shoves it into a CSV. In affected versions this GitHub Action creates a CSV file without sanitizing the output of the APIs. If an alert is dismissed or any other custom field contains executable code / formulas, it might be run when an endpoint opens that CSV file in a spreadsheet program. This issue has been addressed in version `v1`. Users are advised to use `v1` or later. There are no known workarounds for this issue.
