Microsoft Patched Bing Vulnerability That Allowed Snooping on Email

Microsoft Corp. patched a dangerous security issue in Bing last month days before it launched a new artificial intelligence-powered version of the search engine. The problem was discovered by outside researchers at the security firm Wiz Inc. It was created by a mistake in the way that Microsoft configured applications on Azure, its cloud-computing platform, and could be used to gain access to emails and other documents of people who used Bing, the researchers said.
