Android WebView Universal Cross-site Scripting
ghsa·2020-10-02·CVSS 6.5
CVE-2020-6506 [MEDIUM] CWE-79 Android WebView Universal Cross-site Scripting
Android WebView Universal Cross-site Scripting
A universal cross-site scripting (UXSS) vulnerability, CVE-2020-6506 (https://crbug.com/1083819), has been identified in the Android WebView system component, which allows cross-origin iframes to execute arbitrary JavaScript in the top-level document. This vulnerability affects React Native apps which use a `react-native-webview` that allows navigation to arbitrary URLs, and when that app runs on systems with an Android WebView version prior to 83.0.4103.106.
## Pending mitigation
Ensure users update their Android WebView system component via the Google Play Store to 83.0.4103.106 or higher to avoid this UXSS. 'react-native-webview' is working on a mitigation but it could take some time.
