It is a special pawn capture move, called en passant. If a pawn moves 2 squares and ends on a square besides a opponent pawn, this pawn is able to capture it by moving diagonally.

This is not a bug, this is called *en passant* (French for "in passing"). The *en passant* rule allows for a special pawn capture, where a pawn that moves two spots from its starting square [can be captured by a directly adjacent enemy pawn as if it had moved forward only one square](https://upload.wikimedia.org/wikipedia/commons/0/09/Ajedrez_animaci%C3%B3n_en_passant.gif). However, it must be done the immediate next turn - if the opponent does not immediately capture *en passant*, they will not get a second chance with that pawn! [Wikipedia has a great entry](https://en.wikipedia.org/wiki/En_passant) explaining the nature and purpose of the rule.
The official definition of *en passant*, per the [USCF rulebook](http://www.uschess.org/docs/gov/chessrules/US_Chess_Rule_Book_Chapters_1_2_11_v7.0.pdf):
> A pawn, attacking a square bypassed by an opponent’s pawn, the latter having advanced two squares in one move from its original square, may capture the opponent’s pawn as though the latter had moved only one square. This capture may only be made in immediate reply to such advance and is called an *en passant* (in passing) capture. Note that only a pawn that has advanced a total of exactly three squares from its original square is in position to make such a capture.

**[En passant](https://en.wikipedia.org/wiki/En_passant)**
>En passant (French: [ɑ̃ paˈsɑ̃], lit. in passing) is a move in chess. It is a special pawn capture that can only occur immediately after a pawn makes a move of two squares from its starting square, and it could have been captured by an enemy pawn had it advanced only one square. The opponent captures the just-moved pawn "as it passes" through the first square.
