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
WebKit/Source/core/loader/FrameLoader.cpp in Blink, as used in Google Chrome before 52.0.2743.82, does not disable frame navigation during a detach operation on a DocumentLoader object, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.

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

This is a Same Origin Policy (SOP) bypass vulnerability in Blink's FrameLoader.cpp. The flaw occurs because frame navigation is not disabled during a detach operation on a DocumentLoader object, allowing a malicious page to navigate frames to different origins during the detach process and thereby bypass SOP protections.

MitigationUpgrade Google Chrome to version 52.0.2743.82 or later to patch this vulnerability. Users should ensure their browser is updated to the latest 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. Check Google Chrome version
    Open chrome://settings/help or chrome://version to see the installed version number
    Affected if The displayed version is 51.0.2704.106 or lower (any version up to and including 51.0.2704.106)
  2. Identify if using a Chromium-based browser
    Check the browser name and about/version information - many browsers embed Chromium (e.g., Chrome, Opera, Edge legacy, Vivaldi)
    Affected if The browser is based on the Chromium engine and the underlying Chromium version matches the affected range

You are affected if your Chrome or Chromium-based browser version is 51.0.2704.106 or earlier, since the SOP bypass vulnerability exists in those versions of the Blink FrameLoader component.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
