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 10.60 on Windows and Mac OS X does not properly prevent certain double-click operations from running a program located on a web site, which allows user-assisted remote attackers to execute arbitrary code via a crafted web page that bypasses a dialog.

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 confidence

Opera browser versions prior to 10.60 on Windows and Mac OS X contain a flaw in double-click event handling that allows malicious webpages to bypass security dialogs and execute arbitrary programs hosted on external websites. The attack requires user interaction (double-click) but can lead to full code execution.

MitigationUpgrade Opera to version 10.60 or later; if the browser cannot be updated, migrate to a supported modern browser as Opera 10.x is end-of-life.

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
    Search for Opera executable in typical installation paths. On Windows: C:\Program Files\Opera\opera.exe or C:\Program Files (x86)\Opera\opera.exe. On Mac OS X: /Applications/Opera.app
    Affected if Opera browser files exist on the system
  2. Determine the installed Opera version
    Open Opera and navigate to Help > About Opera, or right-click the opera.exe file and select Properties > Details to view the version number
    Affected if Version can be read from the browser or file properties
  3. Compare version to affected range
    Compare the installed version number to the threshold 10.60. Any version below 10.60 (such as 10.54, 10.55, 10.58, or 10.59) is within the affected range
    Affected if Installed version is less than 10.60

The environment is affected if Opera browser version 10.60 or newer is not installed.
