You are probably going to be ok unless someone really wants to hack you. The LastPass hack that exposed passwords of millions of people started from an open port in the home network of one of their engineers.
If you want to be somewhat safer, you could try something like the cloudflare tunnel thing to proxy your home network through their server.
Honestly depends on what he's hosting... Services like shodan are constantly scanning the web and are trying to see what is actually running in the machine.
If he's serving something that's vulnerable and has rce it won't take too long for him to get automatically pwned.
We've seen this with the hafnium Echange vulnerability and all known vulnerable public facing web apps that used log4j.
Regarding the LastPass breach, the second part of the breach was using a very outdated version of Plex. Chances are high that his home machine was already hacked by other malicious actors.
