CodeQL flagged two paths from HTTP-supplied SSH-config fields into
shell + filesystem operations:
* runSSHCommand built "cat $remoteShaFile" / "test -x $remoteBin"
/ "mkdir -p $(dirname $remoteBin)" by direct concatenation; the
arguments come from $HOME on the remote (not the kandev user)
but the analyzer can't see that, and a remote $HOME containing
shell metacharacters would still misparse. Route them through
shellQuote for parity with every other call site in the file.
* dialAuth opened target.IdentityFile straight from the configured
string. Run it through filepath.Clean so any `..` segments slipped
in by string substitution are normalised before os.ReadFile, which
is the canonical mitigation CodeQL recognises here. Behaviour is
unchanged for normal paths.
