No, it actually shows that the fix is in place: above we see the code
evaluated in a “sandbox” (isolated environment) where ‘mkdir’ is
unavailable.
Most likely, the witness /tmp/content-addressed-mirrors-vulnerable was
already present when you ran the test.
Could you try re-running it after doing
“rmdir /tmp/content-addressed-mirrors-vulnerable”?
HTH,
