En Masse Entertainment has posted a brief note on the TERA site to let players know that a potential in-game chat vulnerability has been discovered thanks to a Reddit post (since removed) on the TERA Reddit. En Masse is working to investigate the issue and are working closely with the development team to track down and close the potential exploit. However, at this time, “there is no evidence that the vulnerability is being exploited in these way or that any player info has been compromised”.
