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
An issue in AnkiDroid Android Application v2.17.6 allows attackers to retrieve internal files from the /data/data/com.ichi2.anki/ directory and save it into publicly available storage.

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

AnkiDroid v2.17.6 contains an improper file access control vulnerability that allows attackers to read internal application files from the private /data/data/com.ichi2.anki/ directory and write them to publicly accessible external storage. This exposes potentially sensitive application data that should remain confined to the app's private sandbox.

MitigationDeveloper should review file handling code to ensure internal app data cannot be written to external/public storage, implement proper Android storage permission checks, and use scoped storage APIs to enforce proper data isolation between internal and external storage locations.

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 installed AnkiDroid version
    Run 'adb shell dumpsys package com.ichi2.anki | grep versionName' or check the app's About screen in the application
    Affected if The installed version is 2.17.6 or lower (if earlier versions share the vulnerable code path)
  2. Check if app has external storage write permission
    Run 'adb shell dumpsys package com.ichi2.anki' and look for WRITE_EXTERNAL_STORAGE or MANAGE_EXTERNAL_STORAGE in the permissions section, or inspect the APK's manifest
    Affected if The app holds WRITE_EXTERNAL_STORAGE or MANAGE_EXTERNAL_STORAGE permission enabling write access to shared external storage
  3. Verify internal data directory exists
    Run 'adb shell ls -la /data/data/com.ichi2.anki/' to confirm the app's private sandbox directory is present
    Affected if The /data/data/com.ichi2.anki/ directory exists, indicating the app is installed and has created its private sandbox
  4. Check for files written to public external storage
    Run 'adb shell ls -la /storage/emulated/0/' and search for directories or files belonging to AnkiDroid (typically under Android/data/com.ichi2.anki/)
    Affected if AnkiDroid files appear in shared external storage locations outside the app's private sandbox

A user is affected if AnkiDroid version 2.17.6 is installed and the app has written internal data from /data/data/com.ichi2.anki/ to accessible external storage locations.

Mitigation

Developer should review file handling code to ensure internal app data cannot be written to external/public storage, implement proper Android storage permission checks, and use scoped storage APIs to enforce proper data isolation between internal and external storage locations.
