Tenable iDSecure: denial of service
Fix: upgrade to 4.8.3.0 or later
Control iD iDSecure versions prior to 4.8.3.0 are affected by an unauthenticated Denial of Service.
The /api/dguardintegration/dguardVersion endpoint dereferences DGuard integration login state that may be unset, raising an unhandled null reference exception. The exception is thrown from an asynchronous method that returns void, so it is not observed by a caller and can terminate the iDSecure process.

| Package | Affected | Fixed in |
