Older versions of this mod for Minecraft 1.7 - 1.12 contain a known security vulnerability.
There are updated versions for MC 1.7.10, 1.10.2 and 1.12.2 - if you play those versions please update ASAP.
You can read more about the vulnerability here - https://blog.mmpa.info/posts/bleeding-pipe
I do not recommend playing those old versions on public open servers, you can still safely play in single player. The vulnerability was fixed in BDLib but there are many other mods that are still vulnerable out there as well.
If you do want to play multiplayer I recommend installing one of those 2 mods, though I can't guarantee they completely fix the issue - https://github.com/dogboy21/serializationisbad/releases or https://modrinth.com/mod/pipeblocker
