Video conferencing app Zoom has a foremost security flaw in its Mac client, letting any websites flip for your Mac’s camera with out a warning, security researcher Jonathan Leitschuh claims.
In a blog post Monday, Leitschuh detailed the vulnerability, which he says he’d disclosed to Zoom bigger than ninety days within the past, and the firm aloof hasn’t fastened it.
