I don't think we have any document released yet that describes any full picture.
We do have this statement (and a little more detail inside) in a report by a joint report by the US Intelligence Community (regarding Russian interference with elections):
"We assess with high confidence that Russian military intelligence (General Staff Main Intelligence Directorate or GRU) used the Guccifer 2.0 persona and DCLeaks.com to release US victim data obtained in cyber operations publicly and in exclusives to media outlets and relayed material to WikiLeaks."

But that doesn't explain whether Assange is either a "compromised front" for the GRU or someone else, or more a "useful idiot" to Russian intelligence for their goals.
Nonetheless, I will say, at minimum, Wikileaks and Julian Assange can no longer be seen as a neutral player, at minimum. And not a reliable narrator, either. For example, some of their tweets on the Panama Papers, which in theory I would think would be something they would in theory support, were rather strange, and actually stooped into ridiculous conspiracy theory involving USAID and George Soros (eg https://mobile.twitter.com/wikileaks/status/7176700566505308... and https://mobile.twitter.com/wikileaks/status/7174580643249643...). I generally don't treat sources that delve into conspiracy theory with a whole lot of respect...
