path entries, and other means of path escape, using the well tested and highly reliable path utility built into Node.js. The package.json parsing libraries in use in npm v6.13.3 were updated such that they would sanitize and validate all entries in the bin field to remove leading slashes.
#NPM INSTALL FROM GITHUB BINARY UPDATE#
However, we cannot scan all possible sources of npm packages (private registries, mirrors, git repositories, etc.), so it is important to update as soon as possible. We will continue monitoring, and will take action to prevent any bad actors from exploiting this vulnerability in the future. That does not guarantee that it hasn’t been used, but it does mean that it isn’t currently being used in published packages on the registry. security team has been scanning the registry for examples of this attack, and have not found any published packages in the registry with this exploit. However, as we have seen in the past, this is not an insurmountable barrier.

(That is, not any arbitrary file on the system, but any file in /usr/local/bin.)Ī mitigating factor for both vulnerabilities is that a malicious actor would have to get their victim to install the package with the specially crafted bin entry. In versions of npm prior to 6.13.4 (and all versions of yarn as of this announcement), it was possible for a globally-installed package with a binary entry to overwrite an existing binary in the target install location. In versions of npm prior to 6.13.3 (and versions of yarn prior to 1.21.1), a properly constructed entry in the package.json bin field would allow a package publisher to modify and/or gain access to arbitrary files on a user’s system when the package is installed. Tl dr - Update to npm v6.13.4 as soon as possible on all your systems to fix a vulnerability allowing arbitrary path access. gitconfig in the repository.Updates from the npm team are now published on the In other words, when I run the command git clone, git somehow knows the lfs.url even if I don't have the. I'm not sure if this solution only masks the fact that npm install can't figure out the lfs.url without you explicitly specifying it in. gitconfig you commit to the repository allows the git commands used by npm install to know what lfs.url to use. For Windows, I use Microsoft's credential manager.

You may want to install a credential manager so that you don't have to enter your username and password every time git-lfs goes to retrieve a file. In the directory in which you want to npm install your project, run for example:įor this to work with GitHub, it would appear that the lfs.url to use is:, e.g.: Inside of your repository, run the following command (replace bubblegum with the name of your repo) and then commit the resulting.

My local user account is configured for git this way: $ cat ~/.gitconfigĮdit: In case this is a bug, I've made an issue on GitHub.Īfter poring over the output from git and npm with export GIT_TRACE=1 and npm config loglevel verbose, I believe I have figured out how to get this to work, at least with GitLab (I have since moved from GitHub to GitLab, which also supports Git LFS). *.wav filter=lfs diff=lfs merge=lfs -text *.ogv filter=lfs diff=lfs merge=lfs -text *.png filter=lfs diff=lfs merge=lfs -text gitattributes modified with git lfs track: $ cat. My repo is located at and I use Git LFS to manage binary art and sound assets, so it has a. I verified that git clone from scratch produces the actual binary files instead of the text files. I tried the above npm install command in both cmd and bash and I get the same result. I verified that git-lfs and git lfs work from both cmd and bash. the lfs filters aren't being used and git-lfs is not being called.

It appears npm isn't using my local user account's ~/.gitconfig, i.e. When I run npm install -save npm checks out the text files that git lfs puts in place of the actual assets.
