CVE-2025-67316Public exploitNetwork attack vector

Unintended system activity launches via JavaScript bridge

Published Jan 5, 2026 · Updated Jan 5, 2026

Improper access control in realme Internet browser 45.13.4.1 allows remote attackers to launch Android settings from a crafted webpage. The browser exposes privileged Android Java methods to arbitrary WebView JavaScript through unrestricted addJavascriptInterface(), letting page scripts invoke settings-launch methods without origin or permission checks. A victim must load the page in the affected browser; the demonstrated consequence is opening system settings activities, and realme disputes the finding.
