After Google issued a zero-day exploit warning and pushed an emergency security update for all Chrome users, MetaMask and PancakeSwap urged users to update their browsers and wallet apps as soon as possible. “Chrome has published a security update with a high level of severity. Please upgrade your browser right now, “MetaMask” said in a tweet to its followers.
With nearly 21 million active monthly users, the world’s top non-custodial cryptocurrency wallet was not alone in its pleading. Decentralised exchange PancakeSwap issued a similar warning, advising users to keep their browsers up to date by updating Chrome, Chromium-based Brave, Opera, Edge, and other browsers.
Updates meant for a single security update are uncommon, and especially so for Google, underscoring the gravity of the situation. Because of the extreme level of secrecy surrounding the situation, it’s possible that software security issues were already exploited before the fix was released.
