Thanks for the reply - I didn't think this dev would have bundled it either, but I had to ask to be sure I didn't need to switch to a different docker. I did have authentication set up but I guess that wasn't enough. I don't really need off-network access to calibre so I'll just leave the ports closed for now. I'm also uninstalling it, deleting the calibre appdata folder, and reinstalling to ensure xmrig is gone. If there's anything else I need to check for that you can think of, please let me know. I checked my other docker appdata folders and didn't see any evidence of xmrig and I'll monitor Unraid's processes over the next several days to see if anything reappears.
