CVE-2026-79124Network attack vector

Referrer disclosure via dropped navigation policy

Published Aug 25, 2026 · Updated Aug 25, 2026

Information leak in Google Chrome on Android before 152.0.7977.65 allows remote attackers to expose referrer data via a crafted HTML page. The Intents navigation path drops the referrer policy at the C++-to-Java JNI boundary, and InterceptNavigationDelegateImpl then applies ReferrerPolicy.ALWAYS when replacing the main frame. A victim must load attacker-controlled HTML; external-intent navigation can then transmit referrer details that the originating page's policy was meant to suppress.
