CVE-2026-20996
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 · uneditedUse of a broken or risky cryptographic algorithm in Smart Switch prior to version 3.7.69.15 allows remote attackers to configure a downgraded scheme for authentication.
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 confidenceThis vulnerability in Samsung Smart Switch allows remote attackers to force the application to use a downgraded (weaker) cryptographic scheme for authentication. The broken/risky algorithm could allow attackers to intercept or crack authentication credentials.

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 Smart Switch version on WindowsOpen Control Panel > Programs and Features, or right-click the Smart Switch desktop shortcut and select Properties, then look at the version listed on the Details tabAffected if The version shown is lower than 3.7.69.15
-
Check Samsung Smart Switch version on macOSOpen Finder > Applications > Right-click Smart Switch > Get Info, or run `mdls -name kMDItemVersion /Applications/Smart\ Switch.app` in TerminalAffected if The version shown is lower than 3.7.69.15
-
Verify version from Smart Switch itselfLaunch Smart Switch, then go to Menu (three lines) > Settings > About Smart Switch to view the exact version numberAffected if The displayed version is earlier than 3.7.69.15
You are affected if the installed Samsung Smart Switch version is anything below 3.7.69.15, as only versions prior to this contain the vulnerable cryptographic downgrade capability.

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 · scoped3.7.69.15
Update Smart Switch to version 3.7.69.15 or later, which removes the vulnerable cryptographic downgrade capability.
Smart Switch version 3.7.69.15
- 1. Open the Samsung Smart Switch application on your device
