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 · uneditedImproper input validation in Galaxy Store prior to version 4.6.02 allows local attacker to execute arbitrary script.
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 confidenceImproper input validation in Samsung Galaxy Store Android application versions prior to 4.6.02 allows a local attacker to execute arbitrary script code on the device through insufficiently validated input processed by the app.

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.
-
Verify Galaxy Store app is installedCheck your device for the Samsung Galaxy Store application. On Android, go to Settings > Apps and search for 'Galaxy Store', or use ADB command: `adb shell pm list packages | grep com.sec.android.app.samsungapps`Affected if The Galaxy Store application is present on the device
-
Determine installed Galaxy Store versionOpen Galaxy Store, navigate to Settings > About, or use ADB command: `adb shell dumpsys package com.sec.android.app.samsungapps | grep versionName`Affected if A version number is returned that can be compared to the affected range
-
Compare version to affected rangeTake the installed version number and compare it to 4.6.02.0 using semantic version comparison. Ensure the full version string includes the build number (e.g., 4.6.01.9 would be below 4.6.02.0)Affected if The installed version is numerically lower than 4.6.02.0 in the version code
The device is affected if Samsung Galaxy Store is installed and the running version is earlier than 4.6.02.0.
Generated from the published advisory. Verify against your own configuration.
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 · scoped4.6.02.0
Update Galaxy Store to version 4.6.02 or later via the app store or Samsung firmware updates; organizations should deploy this update through MDM/EMM solutions to ensure fleet-wide coverage.
Galaxy Store version 4.6.02.0
