Impact

Windows users using the sops direct editor option (sops file.yaml) can have a local executable named either vi, vim, or nano executed if running sops from cmd.exe

This attack is only viable if an attacker is able to place a malicious binary within the directory you are running sops from. As well, this attack will only work when using cmd.exe or the Windows C library SearchPath function. This is a result of these Windows tools including . within their PATH by default.

If you are using sops within untrusted directories on Windows via cmd.exe, please upgrade immediately

As well, if you have . within your default $PATH, please upgrade immediately.

Patches

The problem has been resolved in v3.7.1

Now, if Windows users using cmd.exe run into this issue, a warning message will be printed:
vim resolves to executable in current directory (.\vim.exe)
