alt Hacker NewsUPnP allows literally any random piece of software inside your network to open and forward arbitrary ports on your firewall. Bad idea!

Within my risk appetite on trusted network segments. I have bigger issues if malware is operational within the trust boundary, it can do what it needs using outbound connections just fine (recon, lateral movement, etc). Your risk appetite might differ.
Why are you running software that randomly opens firewall ports?
