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
Google Chrome before 13.0.782.107 allows remote attackers to bypass the Same Origin Policy and conduct script injection attacks via unspecified vectors.

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

This is a Same Origin Policy (SOP) bypass vulnerability in Google Chrome versions prior to 13.0.782.107. The vulnerability allows remote attackers to inject scripts into web pages by circumventing the SOP security mechanism that normally isolates content from different origins.

MitigationUpdate Google Chrome to version 13.0.782.107 or later. Organizations should deploy the browser update through their software distribution systems and verify complete coverage across managed endpoints.

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. Identify installed Chrome version
    Navigate to chrome://settings/help or use 'Help > About Google Chrome' to view the version number
    Affected if Chrome version is earlier than 13.0.782.107
  2. Identify installed Safari version
    On Mac: Safari > About Safari. On Windows: Help > About Safari. Check the version number displayed
    Affected if Safari version is earlier than 5.1.1
  3. Identify iOS version for iPhone
    Go to Settings > General > About on the iPhone device and check the version number
    Affected if iOS version is earlier than 5.0 (which includes Safari versions below the fixed release)
