Supergirl isn't slated to air on CBS until November, but a high-quality copy of the pilot has already leaked online, Variety reports.

The first copies of the leaked pilot appeared shortly before 3 a.m. EST on Friday, according to piracy-tracking firm Excipio, as reported by Variety. The episode is available in up to 1080p HD and doesn't appear to have any watermarks.

The leak comes a little more than a week after CBS debuted the first trailer for Supergirl during its 2015-2016 upfront presentation. The six-minute clip has garnered nearly 11 million views on YouTube at the time of this writing.

CBS hasn't commented on the matter yet, but we can only imagine that the network isn't very happy about the leak. CBS' fall schedule is not only bolstered by Supergirl, which stars former Glee star Melissa Benoist in the title role, but it is also one of the most highly anticipated series of the fall of any network.

When you spend all of that time and money keeping a major series premiere like this under wraps in order to build anticipation for its debut, the fact that it's out there five months early for public viewing of course increases the possibility of the show getting spoiled, which leads to people opting out of watching the premiere. Obviously, no network wants that.

Of course, last month, the first four episodes of Season 5 of Game of Thrones leaked just before the premiere, and people still seem to be watching that show. Clearly, these kind of high-profile leaks are problems networks and other TV-producing platforms will have to continue to have and try to solve, if they can.
