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 · unedited
The YI Smart Kami Vision com.kamivision.yismart application through 1.0.0_20231219 for Android allows a remote attacker to execute arbitrary JavaScript code via an implicit intent to the com.ants360.yicamera.activity.WebViewActivity component.

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 confidence

The YI Smart Kami Vision Android application (com.kamivision.yismart) through version 1.0.0_20231219 exposes a WebViewActivity component (com.ants360.yicamera.activity.WebViewActivity) that accepts and executes arbitrary JavaScript code sent via implicit intents, allowing any application or attacker able to send intents to this exported component to achieve remote code execution within the WebView context.

MitigationUpdate to a patched version of the application that implements proper intent source validation and restricts JavaScript execution to explicitly trusted sources only, or disable the exported status of the WebViewActivity if not needed for legitimate inter-app communication.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if YI Smart Kami Vision app is installed
    Run 'adb shell pm list packages | grep -i kamivision' or 'adb shell pm list packages | grep -i yicamera' to find the installed package name
    Affected if Package com.kamivision.yismart or com.ants360.yicamera is present on the device
  2. Get the installed application version
    Run 'adb shell dumpsys package <package_name>' and look for versionName and versionCode, or use 'adb shell pm dump <package_name> | grep -E "versionName|versionCode"'
    Affected if versionName is 1.0.0_20231219 or earlier (no patch applied)
  3. Verify the WebViewActivity component is exported
    Run 'adb shell dumpsys package <package_name>' and look for 'android:exported=true' under the WebViewActivity component (com.ants360.yicamera.activity.WebViewActivity), or decompile the APK and inspect AndroidManifest.xml
    Affected if The WebViewActivity component has android:exported="true" in the manifest
  4. Confirm JavaScript execution is reachable via intents
    Analyze the WebViewActivity code (via decompiled APK) to verify it loads intent data directly into WebView.evaluateJavascript() without validation, or test by sending a crafted intent with JavaScript payload
    Affected if The component accepts intent extras and passes them directly to WebView without sanitization or source validation

The device is affected if the YI Smart Kami Vision app is installed with version 1.0.0_20231219 or earlier AND the WebViewActivity component is exported and processes JavaScript from intent data without validation.
