In danger perhaps, no longer maintaining position (7)

I believe the answer is:

exposed

I'm a little stuck... Click here to teach me more about this clue!

'in danger perhaps' is the definition.
I can't tell whether this defines the answer.

'no longer maintaining position' is the wordplay.
'no longer' becomes 'ex' (prefix meaning former or onetime).
'maintaining position' becomes 'posed' (I can't justify this - if you can you should give a lot more credence to this answer).
'ex'+'posed'='EXPOSED'

Can you help me to learn more?

(Other definitions for exposed that I've seen before include "Unmasked, revealed" , "Like a dummy" , "at mercy of weather" , "Not covered" , "Without protection" .)

I've seen this clue in The Guardian.
