CVE-2020-14130
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSome js interfaces in the Xiaomi community were exposed, causing sensitive functions to be maliciously called on Xiaomi community app Affected Version <3.0.210809
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Xiaomi community app versions prior to 3.0.210809 exposed JavaScript interfaces that allowed malicious calls to sensitive native functions. This typically occurs when WebView components improperly expose @JavascriptInterface-annotated methods to untrusted web content, enabling attackers to invoke privileged mobile functions through crafted JavaScript.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Xiaomi community app versionOpen device Settings > Apps > Xiaomi Community (or Xiaomi Forum) and view the version information displayed under the app name, or query via adb: adb shell dumpsys package com.xiaomi.market | grep versionNameAffected if Version shown is less than 3.0.210809 (for example, 3.0.210701, 2.9.x, or any version without the 3.0.210809 build)
-
Confirm WebView usage in the appInspect app network traffic or review app manifest (via adb: adb shell dumpsys package com.xiaomi.market | grep -i webview) to determine if WebView components load remote web contentAffected if WebView loads untrusted URLs and JavaScript execution is enabled
-
Verify JavaScript interface exposureAnalyze the app APK or decompiled code for @JavascriptInterface annotations on native methods that are reachable from WebView (methods decorated with @JavascriptInterface and accessible via the jsbridge or similar interface names like 'android' or custom bridge names)Affected if Any @JavascriptInterface-annotated methods are exposed to WebView content without additional origin validation
The environment is affected if the Xiaomi community app is installed with a version lower than 3.0.210809 and the app uses WebView to load untrusted content with exposed JavaScript interfaces.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.0.210809
Upgrade Xiaomi community app to version 3.0.210809 or later. If upgrade is not immediately possible, consider disabling JavaScript interface exposure to untrusted WebView content or implementing additional input validation on exposed methods.
3.0.210809 or later
- Open the Xiaomi community app on your device
- Navigate to the app settings or profile section
- Check the current app version under 'About' or 'Version'
- If the version is earlier than 3.0.210809, update the app through the Xiaomi app store, Google Play Store, or by downloading the latest version from Xiaomi's official website
- After updating, verify the version number shows 3.0.210809 or later
