The act of 1917 passed after entering WWI that made it a crime to pass information that would interfere with the success of the us armed forces was the Espionage Act.

Explanation:

The Espionage Act of 1917 is a federal law of the United States that entered into force on June 15, 1917, shortly after the United States joined the First World War. It banned any form of interference and influence in military operations and the support of US enemies during the war, opposing military authority and military orders, and not engaging in recruitment.  In 1919, the Supreme Court of the United States ruled unanimously in Schenck v. United States that this law does not violate freedom of expression.
