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 configuration in Samsung Internet prior to version 21.0.0.41 allows attacker to bypass SameSite Cookie.

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.

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 Samsung Internet browser version
    Open Samsung Internet browser, tap the three-line menu icon, scroll to bottom and tap 'Settings', then tap 'About Internet' to view the version number
    Affected if Version displayed is less than 21.0.0.41
  2. Confirm version in app info
    Go to Android Settings > Apps > Samsung Internet, check the version listed under 'App info'
    Affected if Version shown is below 21.0.0.41
  3. Verify SameSite cookie handling
    This vulnerability is inherent to the browser version itself - no specific cookie configuration can be inspected. The flaw is in the browser's SameSite cookie implementation.
    Affected if Any Samsung Internet version below 21.0.0.41 is affected by the improper SameSite cookie configuration

You are affected if Samsung Internet browser version is below 21.0.0.41, as the improper SameSite cookie configuration exists in those versions.
