CWE: NVD-CWE-Other \u2014 Other
NVD is only using a subset of CWE for mapping instead of the entire CWE, and the weakness type is not covered by that subset.

Code:
func ExtAuthzContextExtensionsRouteID(extAuthzContextExtensions map[string]string) uint64 {
	if extAuthzContextExtensions == nil {
		return 0
	}
	routeID, _ := strconv.ParseUint(extAuthzContextExtensions["route_id"], 10, 64)
	return routeID
}
