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 component com.transsion.tranfacmode.entrance.main.MainActivity in com.transsion.tranfacmode has no permission control and can be accessed by third-party apps which can construct intents to directly open adb debugging functionality without user interaction.

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 · high confidence

The MainActivity component in Transsion's tranfacmode app lacks exported=false or permission controls in its AndroidManifest.xml declaration, allowing any installed third-party app to send intents that launch the activity. This activity, when launched via intent, enables ADB debugging functionality without requiring user interaction or authentication.

MitigationAdd android:exported='false' or implement a signature-level permission (android:permission) on the MainActivity component in AndroidManifest.xml, and add code-level permission verification within the activity before enabling ADB debugging.

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. Identify if tranfacmode app is installed
    Use a package manager to list installed packages and search for 'tranfacmode' - on Android use 'pm list packages | grep tranfacmode' or check app settings
    Affected if The tranfacmode package exists on the device
  2. Extract AndroidManifest.xml from tranfacmode
    Use 'adb shell pm path com.transsion.tranfacmode' to find the APK, then pull and parse AndroidManifest.xml or use 'aapt dump badging [apk_path]' to inspect the MainActivity declaration
    Affected if The AndroidManifest.xml shows MainActivity with no android:exported='false' attribute and no android:permission attribute defined
  3. Verify exported attribute on MainActivity
    Inspect the <activity> tag for MainActivity in the manifest - check if android:exported is absent or set to true
    Affected if android:exported is not set to false or is explicitly set to true
  4. Check for permission requirement on MainActivity
    Inspect the <activity> tag for android:permission attribute - verify if a signature-level or dangerous permission is required
    Affected if No android:permission attribute is present on the MainActivity declaration
  5. Test ADB debugging behavior
    Send an intent to the MainActivity from a separate app or via adb shell am start -n com.transsion.tranfacmode/.MainActivity and observe if ADB debugging settings become enabled without user prompts
    Affected if ADB debugging enables automatically after the intent without requiring user interaction or authentication

The device is affected if the tranfacmode app is present with MainActivity lacking android:exported='false' and any permission protection, allowing unauthorized apps to trigger ADB debugging.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Add android:exported='false' or implement a signature-level permission (android:permission) on the MainActivity component in AndroidManifest.xml, and add code-level permission verification within the activity before enabling ADB debugging.
