Hi Arun,

Researching git-shell, I noticed an example of how Less could be
exploited to increase. privileges:
=> https://hackaday.com/2017/05/10/git-shell-bypass-less-is-more/

It suggests enabling the no-pty flag to mitigate this.

I think it would be great to utilise git-shell (and I am interested in
it for my own activities.

Do anybody have detailed research regarding SSH access with no shell access?

Kind regards,

Jonathan
