New Chrome Privacy Analysis Shows How Fingerprinting and Header Leaks Can Expose Users

Research published April 14, 2026, shows Google Chrome lacks effective anti-fingerprinting protections and exposes users to extensive device fingerprinting (30+ techniques) and client-side tracking (20+ methods). The report documents header-based leaks (ETag, Client Hints), storage-based tracking, and real-world exploitation of CVE-2025-4664 that forwarded full URLs and authentication tokens to third parties; it recommends switching to privacy-focused browsers, using privacy extensions, keeping Chrome updated, and clearing local storage.
