A flaw was found in git, in which a specially-crafted repository that contains a symbolic link may cause just-checked out script to be executed while cloning.
If symbolic link support is disabled in Git (e.g. via git config --global core.symlinks false), the described attack won't work. Likewise, if no clean/smudge filters such as Git LFS are configured globally (i.e. before cloning), the attack is foiled. As always, it is best to avoid cloning repositories from untrusted sources.
