My read (not an expert) is that you are safe if your rsync is only via secure connections, to & from systems where untrusted parties can neither run rsync, nor play clever games with the files which rsync is accessing.
Which (in my paranoid opinion) is pretty much the only secure use case anyway, for code like rsync.
- kees99 2y ago> you are safe if your rsync is only via secure connections Not quite. If server has "command=rsync ..." in ~/.ssh/authorized_keys file, for some ssh key (to allow rsync access, but deny shell access), this vulnerability will allow attacker in possession of that ssh key to go around that restriction, and get shell nonetheless.
