It is being forgotten that all the students in the class 'know' 
because C!m tells them he's impressed (IIRC). certainly Harry and 
Hermione know and any of these Gryffindors (the class I mean not HRH 
necessarily) might mention it to a slytherin who thence conveyed it 
to Snape. Or else told DD in passing (he forsts nothing) or 
McGonaggle etc etc. My point is it wasn't as secret as all that.

Alternatively, Snape might have had it from DD who got it direct 
from Harry by legilimency either during the school year after the 
event or some time during his de-briefing of Harry post graveyard 
where harry had resisted not only any old imperio but one from the 
bad guy himself.

Lastly, yes there are a hundred ways Snape could have got the 
knowledge from a non-Hogwart's source - as has probably been argued, 
including as one of the DE's in the ring at the graveyard or else 
(if you don't believe he was there) as Malfoy's trusted spy at 
Hogwart's (since LM we know was there). If Snape was NOT at the 
graveyard in GoF (and it seems really unlikely, though not 
impossible), then why does Malfoy (Sr or Jr, or LV for that matter) 
still trust him? - he can't have been a very senior DE perhaps, not 
in the 'inner circle'.
