The Premier League board upheld a complaint from Cardiff, who alleged that team information was leaked to officials at Palace prior to the match on April 5.
"The board found that Crystal Palace breached Rule B.16 and has exercised its summary jurisdiction and fined the club."
Rule B.16 states that "in all matters and transactions relating to the League each club shall behave towards each other club and the league with the utmost good faith".
