Loads of important projects have had vulnerabilities that showed up through minor mistakes and oversights. I agree that this shouldn’t happen, but it did. I’d still prefer this project to a closed source editor/IDE and even VSCodes method of having a store full of plugins, many of which are closed source and unverified. The project is in alpha, mistakes and problems are expected. This was obviously an oversight, and after being pointed out, it is being addressed.
Can you elaborate on questionable sources? All the sources I saw were the official sources of the binaries they wanted to download.
