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
A vulnerability affecting F-Secure SAFE browser was discovered. A maliciously crafted website could make a phishing attack with address bar spoofing as the address bar was not correct if navigation fails in a loop.

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

F-Secure SAFE browser has an address bar spoofing vulnerability where a malicious website can trigger a navigation failure loop, causing the address bar to display incorrect URL information. This allows attackers to impersonate legitimate websites for phishing attacks.

MitigationUpdate F-Secure SAFE to the latest version containing the vendor patch. Until patched, users should avoid visiting untrusted websites and manually verify URL authenticity before entering 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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify F-Secure SAFE is installed
    Check for F-Secure SAFE application in the system program list (Windows: Programs and Features, macOS: Applications folder)
    Affected if F-Secure SAFE appears in the installed programs list
  2. Check installed F-Secure SAFE version
    Open F-Secure SAFE, navigate to About or Settings > About section, or right-click the F-Secure icon in system tray and select About to view the version number
    Affected if Version displayed is 19.0 or lower
  3. Confirm Safe Browser component is active
    Look for the Safe Browser feature within F-Secure SAFE - this is typically accessed through the product interface as a protected browsing mode
    Affected if Safe Browser feature is available and has been used for web browsing
  4. Test address bar behavior during navigation failures
    Visit a website and observe if navigation errors cause unexpected address bar updates or display inconsistencies - the vulnerability triggers during a specific navigation failure loop scenario
    Affected if The address bar displays a different URL than what is actually loaded, or fails to update correctly after navigation errors

If F-Secure SAFE version 19.0 or lower is installed and the Safe Browser has been used, the address bar could display incorrect URLs during certain navigation failure scenarios, making the environment vulnerable to phishing attacks.
