An issue was discovered in the routes middleware in OpenStack Neutron
before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. By making API
requests involving nonexistent controllers, an authenticated user may cause
the API worker to consume increasing amounts of memory, resulting in API
performance degradation or denial of service.
