Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the RemoveAmfSubscriptionsInfoProcedure process. An attacker can cause the application to panic and disrupt service availability by sending a crafted DELETE request with a nonexistent subsId after creating a valid EE subscription and obtaining a valid OAuth2 access token. This is only exploitable if the attacker has authenticated access and has performed a preparatory EE-subscription creation for the targeted ueId.
