NVD · uneditedImproper access control vulnerability in Galaxy Store prior to version 4.5.49.8 allows local attackers to install applications from Galaxy Store.
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 confidenceImproper access control vulnerability in Samsung Galaxy Store versions prior to 4.5.49.8 allows local attackers to bypass authorization checks and install applications from the Galaxy Store without proper authentication. The vulnerability requires local device access (physical or via shell) and enables arbitrary app installation with elevated privileges.

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 is installedOn the Android device, open Settings > Apps and search for 'Galaxy Store', or use ADB command: adb shell pm list packages | grep samsungappsAffected if The package com.sec.android.app.samsungapps is present on the device
-
Retrieve the installed Galaxy Store versionUsing ADB: adb shell dumpsys package com.sec.android.app.samsungapps | grep versionName. Alternatively, open Galaxy Store > tap the menu (three lines) > Settings > About to view the version.Affected if A version number is returned from the package manager query
-
Compare version against vulnerable rangeReview the versionName obtained from the previous step. Check if it is less than 4.5.49.8 (for example, 4.5.49.7, 4.5.48.x, etc.)Affected if The installed version is lower than 4.5.49.8, indicating the vulnerable version is present
If Galaxy Store is installed and the retrieved version is below 4.5.49.8, the device is affected by this vulnerability and allows local attackers to bypass authorization for arbitrary app installation.

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 · scoped4.5.49.8
Update Galaxy Store to version 4.5.49.8 or later. For enterprise environments, ensure mobile device management (MDM) policies enforce automatic app updates and verify compliant versions across managed devices.
