Access-restriction bypass via missing WebView authorization
Published Sep 9, 2026 · Updated Sep 10, 2026
Missing authorization in Google Chrome WebView on Android before 153.0.8010.36 allows remote attackers to bypass system access restrictions. The public record does not identify the WebView request path, protected operation, or omitted authorization check beyond crafted network traffic. Exploitation requires social engineering and user interaction; Google has not described the exact restriction bypassed or the resulting access.
