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
Cross-domain vulnerability in Mozilla Firefox allows remote attackers to access restricted information from other domains via an object tag with a data parameter that references a link on the attacker's originating site that specifies a Location HTTP header that references the target site, which then makes that content available through the outerHTML attribute of the object. NOTE: this description was based on a report that has since been retracted by the original authors. The authors misinterpreted their test results. Other third parties also disputed the original report. Therefore, this is not a vulnerability. It is being assigned a candidate number to provide a clear indication of its status

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

Reported cross-domain vulnerability in Mozilla Firefox where an object tag with a data parameter could potentially access restricted information from other domains via outerHTML attribute. However, the original report was retracted by the authors who admitted to misinterpreting their test results, and third parties disputed the findings. This is officially not considered a valid vulnerability.

MitigationNo specific remediation required as this is not a valid vulnerability. Standard browser update practices remain recommended.

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 Firefox version
    Open a new tab and type 'about:support' in the address bar. Look for the 'Application Basics' section showing the 'Version' number.
    Affected if The version matches any of these: 0.8, 0.9, 0.9.1, 0.9.2, 0.9.3, 0.10, 0.10.1, 1.0, 1.0.1, 1.0.2, 1.0.3, or 1.0.4
  2. Confirm via Help menu
    Click Help > About Mozilla Firefox to view the exact version number displayed in the dialog window.
    Affected if The version shown matches any in the affected list above
  3. Check application binary
    On Windows, right-click the Firefox executable (firefox.exe), select Properties, then look at the Details tab for the File Version. On macOS, right-click the Firefox application, select Get Info, and check the Version field.
    Affected if The file version corresponds to any of the listed affected versions

You are only affected if you are running one of the specific Firefox versions listed (0.8 through 1.0.4), though note this CVE was officially retracted and is not considered a valid vulnerability.
