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
Improper access control vulnerability in cloudNotificationManager.java SmartThings prior to version 1.7.89.0 allows attackers to access sensitive information via SHOW_PERSISTENT_BANNER broadcast.

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 confidence

Improper access control in cloudNotificationManager.java allows unauthorized access to sensitive information through the SHOW_PERSISTENT_BANNER broadcast mechanism in SmartThings app versions prior to 1.7.89.0. Attackers can exploit this to read sensitive data without proper authentication or authorization checks.

MitigationUpgrade SmartThings to version 1.7.89.0 or later which contains proper access control validation for the broadcast handler. If unable to upgrade immediately, consider disabling or restricting the SHOW_PERSISTENT_BANNER broadcast capability.

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. Check SmartThings app version on Android
    Open Settings > Apps > SmartThings > App info or tap the app in the Play Store to view the version number
    Affected if The displayed version is lower than 1.7.89.0
  2. Check SmartThings app version on iOS
    Open the App Store, search for SmartThings, or go to Settings > General > iPhone Storage > SmartThings to view version
    Affected if The displayed version is lower than 1.7.89.0
  3. Verify version via SmartThings app
    Open the SmartThings app, go to Settings (gear icon) > About SmartThings to view the app version
    Affected if The version shown is below 1.7.89.0

A user is affected if the installed SmartThings app version is lower than 1.7.89.0, as earlier versions contain the improper access control vulnerability in cloudNotificationManager.java for the SHOW_PERSISTENT_BANNER broadcast mechanism.
