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.
-
Check Samsung Email app versionOpen Settings > Apps > Samsung Email > Version information, or open Galaxy Store/Google Play Store and search for Samsung Email to view the installed versionAffected if The displayed version number is less than 6.1.90.4
-
Verify app sourceDetermine whether Samsung Email was installed from Galaxy Store, Google Play Store, or pre-installed as a system appAffected if The app is a pre-installed system app that cannot be updated through stores
-
Confirm data storage exposure riskReview whether the device has been rooted or allows third-party apps with broad permissions to access app sandbox directoriesAffected if The device has root access or third-party apps have been granted permissions that could bypass Android sandboxing
If the installed Samsung Email version is below 6.1.90.4 and the device allows potential unauthorized access to app sandbox directories, the environment is affected by this vulnerability.
