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 allows remote attackers to spoof the address field by triggering a page reload followed by a redirect to a different domain.

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 contains an address bar spoofing vulnerability where a remote attacker can manipulate the browser to display one domain in the address field while rendering content from a different domain. This is achieved by triggering a page reload followed by a redirect, causing the address bar to remain anchored to the original domain.

MitigationUpgrade Opera to version 11.62 or later. If using a maintained Chromium-based Opera variant, ensure it receives current security updates. For web applications, implement Content Security Policy headers to mitigate phishing risks from address spoofing.

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 installed Opera version
    Open Opera and navigate to Help > About Opera, or run 'opera --version' from command line. On Windows, the version may also be visible in Add/Remove Programs.
    Affected if The displayed version is 11.61 or lower, or matches any of these: 5.0, 5.02, 5.10, 5.11, 5.12, 6.0, 6.1, 6.01, 6.02, 6.03, 6.04
  2. Confirm browser engine type
    Check if the installed Opera is the legacy Presto-based engine (versions 12 and earlier) or the newer Chromium-based Opera (version 15 and later). This can be determined from the version number and About dialog.
    Affected if The browser is Opera versions 12 or earlier using the Presto rendering engine, as the Chromium-based variants are not affected by this specific flaw.
  3. Identify if address bar manipulation is possible
    Attempt to reproduce the vulnerability by loading a page, triggering a reload (F5 or Ctrl+R), and immediately following with a JavaScript redirect (window.location) before the reload completes. Observe whether the address bar displays the original domain while content loads from a different origin.
    Affected if The address bar shows the original domain while content from a different domain renders, confirming the spoofing vulnerability is present.

The environment is affected if Opera with Presto engine version 11.61 or earlier (including the listed older versions) is installed and the address bar can be made to display one domain while rendering content from a different domain.

From vendor data
Upgrade available Upgrade to a release after 11.61
Interim mitigation

Upgrade Opera to version 11.62 or later. If using a maintained Chromium-based Opera variant, ensure it receives current security updates. For web applications, implement Content Security Policy headers to mitigate phishing risks from address spoofing.
