WhatsApp warns of two vulnerabilities that could allow attackers to execute code remotely. The vulnerabilities have been addressed in recent versions of the app for iOS and Android, starting with version number 126.96.36.199.
According to WhatsApp, the first security vulnerability can occur during video calling. The second vulnerability occurs when opening a specially modified video file.
WhatsApp does not provide further details about both leaks, which were discovered by its own employees. According to a spokesperson, there are “no indications” that the vulnerabilities have already been actively exploited.
