The following table provides a summary description of what the permission allows, and discusses the risks of granting code the permission.Permission Target Name What the Permission Allows Risks of Allowing this Permission attachVirtualMachine Ability to attach to another Java virtual machine and load agents into that VM. This allows an attacker to control the target VM which can potentially cause it to misbehave. createAttachProvider Ability to create an AttachProviderinstance.This allows an attacker to create an AttachProvider which can potentially be used to attach to other Java virtual machines.
