A cybersecurity researcher disclosed technical details of multiple high severity vulnerabilities he discovered in WhatsApp, which, if exploited, could have allowed remote attackers to compromise the security of billions of users in different ways.
When combined together, the reported issues could have even enabled hackers to remotely steal files from the Windows or Mac computer of a victim using the WhatsApp desktop app by merely sending a specially crafted message.
Discovered by PerimeterX researcher Gal Weizman and tracked as CVE-2019-18426, the flaws specifically resided in WhatsApp Web, a browser version of the world’s most popular messaging application that also powers its Electron-based cross-platform apps for desktop operating systems.
