CVE-2026-20994
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 · uneditedURL redirection in Samsung Account prior to version 15.5.01.1 allows local attackers to potentially get access token.
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 confidenceURL redirection vulnerability in Samsung Account app versions prior to 15.5.01.1 allows a local attacker with physical or privileged local access to manipulate redirect URLs and potentially intercept access tokens. The vulnerability stems from insufficient validation of redirect targets in the application's authentication flow.

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 Account app versionOn the Android device, go to Settings > Apps > Samsung Account and view the version information. Alternatively, use ADB: adb shell dumpsys package com.samsung.android.account | grep versionNameAffected if The displayed version is lower than 15.5.01.1
-
Confirm authentication redirect behaviorInspect the Samsung Account app's webview or browser-based authentication flow for redirect URL handling - this typically requires dynamic analysis or source code review of the authentication moduleAffected if The app does not validate redirect URLs against an allowlist before passing them to the OAuth flow
-
Assess local access exposureDetermine if the device allows side-loaded applications or has been rooted, as the attacker needs physical access or privileged local access to exploit this vulnerabilityAffected if The device permits installation from untrusted sources or has been compromised with elevated privileges
The environment is affected if Samsung Account app version is below 15.5.01.1 and the device allows local physical or privileged access that could enable redirect URL manipulation.
