If you’re running version 5.6.0 or 5.6.1, downgrade immediately.
For me I feel like we have not had any big security stuff since the whole log4j thing. While this seems bigger they have caught it relatively early. I feel like more people had to panic patch Minecraft servers with log4j.
maybe the libwebp vulnerability deserves a honorable mention, although i don’t think it has had as big an impact, it could’ve been way worse.
My only reservation is that this compromised contributor has been working on the project for a few years. I hope that this is the end of the tunnel and there aren’t more issues to be uncovered with further analysis.
Its easy to spiral out of control thinking about how the practice that got us this backdoor is something that is used all over the open source community to build code. In the end we can only evaluate what is in front of us and pray the things lurking in the shadows are something we can deal with when they expose themselves.
