It sort of looks like the smallest (threaded) cog is over-hanging the end of the freehub body, possibly a sign that the freehub body isn't meant for the 7s cassette that has been installed on it(???).
If there is less than three full turns of engagement of the smallest cog on the freehub body, I would call that dangerous.
Normally there is well more than three full turns of engagement.
