The location of `connect.exe`\u0027s config file is hard-coded as `/etc/connectrc` which will typically be interpreted as `C:\\etc\\connectrc`. Since `C:\\etc` can be created by any authenticated user, this makes `connect.exe` susceptible to malicious files being placed there by other users on the same multi-user machine. The problem has been patched in Git for Windows v2.40.1. As a workaround, create the folder `etc` on all drives where Git commands are run, and remove read/write access from those folders. Alternatively, watch out for malicious `\u003cdrive\u003e:\\etc\\connectrc` files on multi-user machines."
