A team of Security researchers discovered a vulnerability in the popular end-to-end encrypted Signal messaging app. This vulnerability allowed remote attackers to inject malicious code on the recipients’ Signal desktop app just by sending them a message—without requiring any user interaction.
Signal has identified and patched the flaw and released the updated Signal Desktop version 1.11.0 for Windows, macOS, and Linux users. The signal app has an auto-update mechanism, so most users must have the update already installed. You can read this guide to ensure if you are running an updated version of Signal.
