Leaked, oozed (6)
I believe the answer is:
seeped
This clue is a double definition.
'leaked' is the first definition.
(I've seen this in another clue)
'oozed' is the second definition.
('seep' can be a synonym of 'ooze')
(Other definitions for seeped that I've seen before include "Sweated" , "Oozed slowly out" , "Leaked through small openings" , "Oozed or percolated" , "Exuded" .)
