Users of Twitter's popular web app TweetDeck are encouraged to log out of their account right away.
Users reported on Wednesday morning that the app was creating pop-up alerts all by itself. The issue seemed to be affecting those who use TweetDeck on Google Chrome, but some reports show that other versions were affected as well, according to the tech blog Gigacom.
Mashable reported that the service has a security flaw that could allow hackers to gain access to user accounts. TweetDeck confirmed on Twitter in the afternoon that the issue has been fixed.
In addition to logging out of and logging back into the app, users are encouraged to remove access to TweetDeck from the Twitter app before using the service again.
A security issue that affected TweetDeck this morning has been fixed. Please log out of TweetDeck and log back in to fully apply the fix.
