CVE-2026-21035
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 Samsung Plus TV prior to version 1.0.28.6 allows remote attackers to access sensitive information.
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 confidenceSamsung Plus TV versions prior to 1.0.28.6 contain an improper input validation vulnerability that allows remote attackers to bypass input sanitization checks and access sensitive information. The lack of proper input validation on specific entry points enables unauthenticated attackers to potentially retrieve confidential data from the television system.

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.
-
Confirm Samsung Plus TV is installedAccess your Samsung TV settings, navigate to Apps or Application Manager, and verify Samsung Plus TV is listed among installed applications.Affected if Samsung Plus TV application is present on the device
-
Locate the installed version numberWithin the Samsung Plus TV app settings or the TV system information section, find the current version of the Samsung Plus TV application. This is typically displayed as a version string in the app about or system apps menu.Affected if Unable to determine the version number from the TV system or app settings
-
Compare version against vulnerable rangeCheck the installed version against the affected range: any version lower than 1.0.28.6 is vulnerable. Note the exact version displayed (for example, 1.0.28.0, 1.0.27.5, etc.).Affected if Installed version is less than 1.0.28.6 (for example, 1.0.28.0, 1.0.27.0, etc.)
-
Verify network exposure of the TVCheck your Samsung TV network settings to determine if it is accessible on your local network or directly exposed to the internet. Confirm whether remote connections are possible.Affected if TV is network accessible and the input validation vulnerability could be exploited remotely
You are affected if Samsung Plus TV is installed and the installed version is lower than 1.0.28.6, especially if the TV is network accessible.

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 · scoped1.0.28.6
Upgrade Samsung Plus TV to version 1.0.28.6 or later to obtain the patched build with proper input validation. If upgrading is not immediately possible, restrict network exposure of the TV and monitor for suspicious access patterns.
1.0.28.6
- Open the Samsung Plus TV application
- Navigate to Settings or About section
- Check the current application version
- Update the application to version 1.0.28.6 or later through the app store or system update mechanism
- Verify the update was successful by checking the version number again
