Cures can be nasty for pirates (10)

I believe the answer is:

buccaneers

'pirates' is the definition.
('buccaneer' can be a synonym of 'pirate')

'cures can be nasty' is the wordplay.
'nasty' is an anagram indicator.
'cures'+'can'+'be'='curescanbe'
'curescanbe' anagrammed gives 'BUCCANEERS'.

'for' is the link.

(Another definition for buccaneers that I've seen is " Piratical adventurers".)

I've seen this clue in the Sydney Morning Herald.
