- GHSA-m3mq-f375-5vgh
details: vantage6 is an open-source infrastructure for privacy preserving analysis.
  The JWT secret key in the vantage6 server is auto-generated unless defined by the
  user. The auto-generated key is a UUID1, which is not cryptographically secure as
  it is predictable to some extent. This vulnerability is fixed in 4.11.0.
