Meta Platforms Inc. has addressed a critical security vulnerability in the Windows version of WhatsApp, identified as CVE-2025-30401. This flaw allowed attackers to execute malicious code on targeted devices through a spoofing attack, exploiting the file-attachment option in the app, specifically using attachments in MIME format. Users are urged to update to version 2.2450.6 to mitigate the risk. In addition to the security update, WhatsApp is rolling out new features to enhance user experience across chats, calls, and channels. These include real-time online indicators for group chats, customizable group notifications, expanded event functionality, and improvements in call quality and video capabilities. iPhone users can now use document scanning directly within the app and set WhatsApp as their default messaging and calling app. The update also allows for HD video calls. OpenAI has introduced a new memory feature for ChatGPT, allowing it to reference users' past conversations to provide more personalized responses. This feature, initially available to ChatGPT Pro and Plus subscribers, aims to enhance the conversational context and user experience. Users can opt out of this feature in the settings if they prefer not to have their conversations saved.
