WhatsApp Patches Zero-Click Zero-Day Exploit in iOS
🔒 WhatsApp has patched a critical zero-day (CVE-2025-55177) affecting linked-device synchronization that could allow processing of content from an arbitrary URL on a target device. The vendor says the flaw, when combined with an Apple OS-level out-of-bounds write (CVE-2025-43300), may have been exploited in a targeted, sophisticated zero-click attack. Apple patched the related OS issue on August 20. Users should apply the updated WhatsApp and WhatsApp Business iOS and Mac clients immediately.
