Summary

ghas-to-csv vulnerable to Improper Neutralization of Formula Elements in a CSV File

Details

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 👇🏻

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).
