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 Taidii Diibear Android application 2.4.0 and all its derivatives allow attackers to obtain user credentials from an Android backup because of insecure application configuration.

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 Taidii Diibear Android application 2.4.0 and all derivatives have insecure backup configuration that allows attackers to obtain user credentials through Android backup extraction (adb backup or similar tools). The application likely has android:allowBackup enabled without proper data encryption, exposing sensitive user authentication data.

MitigationSet android:allowBackup="false" in AndroidManifest.xml and ensure any remaining sensitive data is encrypted using Android Keystore or equivalent cryptographic protection to prevent credential exposure through backup files.

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. Confirm Taidii Diibear app is installed
    Check installed applications on the Android device and identify the Taidii Diibear package. Note the installed version number.
    Affected if Version 2.4.0 is installed and the application contains user credentials
  2. Extract the application APK
    Use adb pull or a file explorer to obtain the APK file from /data/app/ or the installed application package.
    Affected if The APK is successfully retrieved for analysis
  3. Inspect AndroidManifest.xml for allowBackup setting
    Decompile the APK using apktool or similar tool, then open AndroidManifest.xml and locate the android:allowBackup attribute in the <application> tag.
    Affected if android:allowBackup is set to true, set to a non-false value, or is missing (defaults to true in Android)
  4. Check for sensitive data encryption
    Analyze the application code and local storage directories (/data/data/<package>/shared_prefs/, databases in /data/data/<package>/databases/) to determine if user credentials are stored without encryption.
    Affected if User authentication data is stored in plain text or with weak encryption without Android Keystore protection

The environment is affected if Taidii Diibear version 2.4.0 is installed and the application has android:allowBackup enabled or defaults to enabled while storing credentials without Android Keystore encryption.
