Peril of doctored dossier (7)
I believe the answer is:
profile
'dossier' is the definition.
(I've seen this before)
'peril of doctored' is the wordplay.
'doctored' indicates an anagram.
'peril'+'of'='perilof'
'perilof' is an anagram of 'PROFILE'.
(Other definitions for profile that I've seen before include "record" , "Short biographical sketch" , "Side view; portrait in words" , "image" , "View from one side" .)
