Gravitee API Management hasta la versión 4.12.22 contiene una vulnerabilidad de omisión de autenticación que permite a atacantes remotos no autenticados suplantar a cualquier usuario falsificando JWT firmados con el valor predeterminado jwt.secret incluido en el producto. Los atacantes que conozcan el ID de un usuario existente pueden firmar un token HS256 con ese sujeto y presentarlo como token de portador (bearer) a la API de gestión, suplantando a administradores para obtener control total de la plataforma.
