CVE-2025-43866

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.

Summary		(es) Vantage6 es una infraestructura de código abierto para el análisis que preserva la privacidad. La clave secreta JWT en el servidor Vantage6 se genera automáticamente, a menos que el usuario la defina. Esta clave es un UUID1, que no es criptográficamente seguro, ya que es predecible hasta cierto punto. Esta vulnerabilidad se corrigió en la versión 4.11.0.
