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 access control vulnerability in Samsung Smart Things mobile application versions prior to 1.7.93 allows an authenticated attacker to bypass authorization checks and invite other users to shared Smart Things locations or devices without ownership permission. This is a classic broken access control (IDOR-style) vulnerability where the application fails to validate that the requester has appropriate owner-level privileges before processing invitation requests.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Smart Things mobile app installationLocate the Samsung Smart Things application on the mobile device (Android or iOS). On Android: Settings > Apps > SmartThings. On iOS: Browse app library or search for SmartThings.Affected if Smart Things app is installed on the device
-
Determine installed app versionCheck the installed version number. On Android: Open Play Store, search SmartThings, view version under app info. On iOS: Open App Store, search SmartThings, tap the app to see version details. Alternatively, within the app: tap Profile > Settings > About SmartThings.Affected if Unable to retrieve version information (app may be corrupted or from unauthorized source)
-
Compare version against vulnerable rangeCompare the installed version number to the affected range: versions prior to 1.7.93. Note that version formats may vary (e.g., 1.7.92, 1.7.85, 1.7.50).Affected if Installed version is less than 1.7.93 (for example: 1.7.92, 1.7.90, 1.6.x, etc.)
A user is affected if they have the Samsung Smart Things mobile application installed with a version number lower than 1.7.93.
