Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| GitHub Actions | some-natalie/ghas-to-csv | < 1 | 1 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
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. The data flow looks like this 👇🏻
```mermaid
graph TD
A(Repository) -->|developer dismissal, other data input| B(GitHub Advanced Security data)
B -->|ghas-to-csv| C(CSV file)
C -->|spreadsheet program| D(endpoint executes potentially malicious code)
```
### Patches
Please use version `v1` or later. That tag moves from using `csv` to `defusedcsv` to mitigate this problem.
### Workarounds
There is no workaround. Please upgrade to using the latest tag, `v1` (or later).
