Her result at 2007 European Women's Championship qualified her for the Women's World Chess Championship 2008 in Nalchik, Russia. The final armageddon tiebreak game of her first round match against Monika Soćko ended in controversy. Foisor only needed a draw to advance to the next round, and reached a drawn ending with each player having only a king and a knight. Although Foisor ran out of time, the arbiter initially ruled that the game was a draw. Soćko appealed, pointing out that what matters is not whether checkmate can be "forced", but rather if it is "possible". Soćko won the appeal and advanced to the next round, eliminating Foisor from the event.
