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 agile wallboard gadget in Atlassian Jira before version 7.8.1 allows remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the name of quick filters.

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

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 Jira version
    Navigate to Jira administration > Applications > Jira software or access /rest/api/2/serverInfo endpoint to retrieve the installed Jira version number
    Affected if The installed version is any release before 7.8.1 (e.g., 7.8.0, 7.7.x, 7.6.x, etc.)
  2. Identify agile wallboard usage
    Review project dashboards and check if any dashboards contain the 'Agile Wallboard' gadget. Look for dashboards with the wallboard gadget added in the project or global context
    Affected if The agile wallboard gadget is present on any dashboard in the Jira instance
  3. Inspect quick filter configurations
    Access any active wallboard gadget, click on the quick filters panel, and examine the names assigned to quick filters. Check for any unusually named filters containing HTML tags, script elements, or javascript: URIs
    Affected if Any quick filter name contains raw HTML, script tags, or suspicious JavaScript code that was not escaped when rendered

The environment is affected if Jira version is below 7.8.1 AND the agile wallboard gadget with quick filters is in use, regardless of whether malicious content is currently observable in the filter names.
