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
Opera before 11.62 does not ensure that a dialog window is placed on top of content windows, which makes it easier for user-assisted remote attackers to trick users into downloading and executing arbitrary files via a download dialog located under other windows.

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

Opera before 11.62 fails to enforce proper window stacking for download dialogs, allowing them to be positioned behind other windows. This UI confusion enables attackers to obscure the download dialog and trick users into downloading and executing malicious files.

MitigationUpgrade Opera to version 11.62 or later to ensure download dialogs are always displayed on top of other windows.

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 if Opera Browser is installed
    Look for Opera browser on the system (common locations: Program Files on Windows, /usr/bin or /opt on Linux, Applications folder on macOS). Check for opera.exe or opera binary.
    Affected if Opera Browser is present on the system
  2. Determine the installed Opera version
    Open Opera, then access Help > About Opera to view the version number. Alternatively, run 'opera --version' from command line on Linux or check the executable properties on Windows.
    Affected if Version displayed is 11.61 or earlier, or any of these specific versions: 5.0, 5.02, 5.10, 5.11, 5.12, 6.0, 6.1, 6.01, 6.02, 6.03, 6.04
  3. Confirm the vulnerability applies to this installation
    Verify that the identified version is within the affected range (11.61 or lower). The vulnerability requires the download dialog feature to be accessible, which is default behavior in affected versions.
    Affected if Installed version is 11.61 or lower and the browser is used for downloading files

A user is affected if Opera Browser version 11.61 or any of the listed older versions (5.0 through 6.04) is installed and used for web browsing with download functionality.
