uBlock Origin ships with a "Block Outsider Intrusion into LAN" filter that I believe is enabled by default. I don't know if it works on the neutered Chrome version, but on Firefox it works so well I've had to add a few whitelists for cases where I do want access to LAN or localhost.
disabled by default, because it can break stuff which is not explicitly allowlisted
And even if you enable it, it has an extensive allowlist that probably includes things you don't want.
