Resource Pack Whitelist

Preventing side-channel IP leakage

When a server sends a resource pack request packet to a client, the client will send an HTTP request to whatever URL the server says the resource pack is hosted at. Because those URLs can be attacker-controlled, a server owner would be able to extract the IP address of any client accepting the server's resource pack.

MineKeep prevents IP leakage from happening this way by employing a resource pack host whitelist. Resource pack requests can only reference packs hosted on a set list of trusted domains. All other requests will be dropped.

Here are the whitelisted domains:

• *.server.minekeep.gg (For self-hosted packs)

• download.mc-packs.net

• github.com

• raw.githubusercontent.com

• atlas.oraxen.com (For Oraxen)

• nauticalhosting.org (For NauticalRanks)

• lobfile.com (For ItemsAdder)

If you need to serve a resource pack. Make sure it originates from one of these domains.
