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
The Edit upload resource for a review in Atlassian Fisheye and Crucible before version 4.7.0 allows remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the wbuser parameter.

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.

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 Fisheye version via admin interface
    Log into the Fisheye admin console, navigate to the 'About' or 'Server Info' page (typically at /admin/about/), and locate the version number displayed there.
    Affected if The displayed version is below 4.7.0 (e.g., 4.6.x, 4.5.x, etc.)
  2. Check Fisheye version via REST API
    Query the Fisheye REST endpoint: GET /rest-services-fe/latest/server/info - the response JSON contains a 'version' field.
    Affected if The version field in the response is below 4.7.0
  3. Check Crucible version via admin interface
    Log into the Crucible admin console, navigate to the 'About' or 'Server Info' page (typically at /crucible/admin/about/), and locate the version number displayed there.
    Affected if The displayed version is below 4.7.0 (e.g., 4.6.x, 4.5.x, etc.)
  4. Check Crucible version via REST API
    Query the Crucible REST endpoint: GET /rest-services-fisheye/latest/server/info - the response JSON contains a 'version' field.
    Affected if The version field in the response is below 4.7.0

If any installed instance of Fisheye or Crucible reports a version lower than 4.7.0, the environment is vulnerable to the reflected XSS via the wbuser parameter.
