Name of the Vulnerable Software and Affected Versions vantage6 versions prior to 4.0.0

Description vantage6 is a privacy-preserving federated learning infrastructure. The issue arises from the use of pickle as the default serialization module, which has known security issues. All users of vantage6 that post tasks with the default serialization are affected. As a workaround, users may specify JSON serialization.

Recommendations For versions prior to 4.0.0, update to version 4.0.0, which contains a patch. As a temporary workaround, consider specifying JSON serialization instead of the default pickle serialization.
