WhatsApp is rolling out New Year 2026 features including a new sticker pack, special video call effects like fireworks and confetti, animated confetti reactions, and festive status updates. These limited-time additions aim to enhance holiday celebrations. Separately, India's CERT-In issued a high-severity advisory for a critical vulnerability in WhatsApp's device-linking feature, dubbed "GhostPairing," which could allow attackers to gain complete control of user accounts without authentication.
