Next episode of 'Game of Thrones' leaked online, courtesy of HBO Spain

UPDATE: Aug. 16, 2017, 3:42 p.m. BST HBO has released this statement about the leak:

We have learned that the upcoming episode of Game of Thrones was accidentally posted for a brief time on the HBO Nordic and HBO España platforms. The error appears to have originated with a third party vendor and the episode was removed as soon as it was recognized. This is not connected to the recent cyber incident at HBO in the U.S.

It turns out you don't need hackers to spoil the next episode of Game of Thrones -- HBO Spain is here for your needs!

This season's episode 6, due to air Sunday, has leaked online after HBO Spain accidentally made it available to subscribers for an hour before it was removed.

Reddit user Kingrdgz posted a screenshot of the episode on /r/FreeFolk (SPOILERS!), a popular Game of Thrones discussion board that isn't moderated. He even posted a 2 minute video from the leak (WARNING, SPOILERS!)

Other users in the thread shared links of the episode being livestreamed on Instagram, YouTube, and Twitch. All the links have been removed at the time of publication.

Game of Thrones fan website Watchers on the Wall confirmed that spoilers are being shared on social media:

Episode 4 of the season, titled "The Spoils of War", was leaked online earlier this month and also appeared on r/FreeFolk.

Mashable has reached out to HBO to confirm the leak.

Be careful out there. Twitter is dark and full of spoilers. You've been warned.
