WikiLeaks is an international whisteblower non-profit organization that publishes submissions of private, secret, and classified media from anonymous news sources and news leaks. Its website, launched in 2006 and run by The Sunshine Press, claimed a database of more than 1.2 million documents within a year of its launch. This can include things such as the War Logs.
Source- Wikipedia, and other stuff.
WikiLeaks obtained the documents from anonymous sources. They did not seek permission from governments to publish them, but rather published them for the public good.
Sensitive documents are "leaked" to them from anonymous sources, most likely within governments.
WikiLeaks is a non-profit whistleblowing website that publishes leaks of government documents from anonymous sources. Although it launched as an editable wiki, it no longer accepts edits or comments.

As of my last update, WikiLeaks has released millions of documents, amounting to several terabytes of data. Estimates suggest that the total size of the WikiLeaks database, including all its publications, exceeds 10 terabytes. However, the exact size can vary as new documents are added and older ones are archived or removed. For the most current figures, it's best to consult WikiLeaks directly or check recent analyses.

Reading WikiLeaks itself is not illegal, as it is a website that publishes leaked documents and information. However, accessing or sharing classified or confidential information from WikiLeaks could potentially be illegal, depending on the circumstances and laws in your country. It is important to be aware of the legal implications of accessing and sharing sensitive information.
On days when WikiLeaks releases new documents (such as November 28, 2010 when the US State Department cables were released) the website experienced a Dos or denial of service attack by various hackers and organizations and basically overloaded the wikileaks server. In some countries (United Arab Emirates, Thailand, China and Australia) WikiLeaks has been blocked before. Recently WikiLeaks changed domain names from wikileaks.org to wikileaks.ch ... try the new domain.
Some documents that were leaked contained sensitive references to foreign heads of state. This could anger them into taking revenge on us, or worse. So to answer your question, yes, WikiLeaks can very well be a threat to U.S. National Security.
