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
Visual truncation vulnerability in KDE Konqueror 3.5.7 allows remote attackers to spoof the URL address bar via an http URI with a large amount of whitespace in the user/password portion.

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

Visual truncation vulnerability in KDE Konqueror 3.5.7 allows remote attackers to spoof the URL address bar by embedding a large amount of whitespace in the user/password portion of an http URI, causing the browser to display a misleading URL to users.

MitigationUpgrade Konqueror to a version newer than 3.5.7, or upgrade the entire KDE environment to a current version.

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. Confirm Konqueror is installed
    Check for Konqueror browser on the system - look for the konqueror binary or package using system package managers or file system queries
    Affected if Konqueror browser is present on the system
  2. Identify the installed Konqueror version
    Run the command to check Konqueror version, typically via package manager (e.g., rpm -q konqueror, dpkg -l konqueror, or konqueror --version)
    Affected if The installed version is exactly 3.5.7
  3. Verify the URL display behavior
    Since this is a display spoofing vulnerability, the flaw manifests when Konqueror renders URLs containing excessive whitespace in the user/password portion of a URI - this would require testing with a crafted URL or code inspection of the URL rendering component
    Affected if Users can be presented with URLs where whitespace in the userinfo section causes visual truncation in the address bar, misleading them about the actual destination domain

A user is affected if Konqueror version 3.5.7 is installed and users view URLs in the browser, as the address bar can be visually spoofed through whitespace manipulation in the URL userinfo portion
