A glitch in Zoom s screen-sharing feature shows parts of presenters screens that they did not intend to share potentially leaking emails or passwords. A security blip in the current version of Zoom could inadvertently leak users data to other meeting participants on a call. However, the data is only leaked briefly, making a potential attack difficult to carry out. The current Zoom client version, 5.5.4 (13142.0301), for Windows is still vulnerable to the issue.
