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 Jira installation version
    Access Jira administration or check the <jira-install>/atlassian-jira/WEB-INF/classes/application-info.xml file, or run: cd /opt/jira && ./bin/version.sh (path may vary)
    Affected if Version is below 7.13.9 OR version is 8.0.0 through 8.4.1 (8.4.2 and later are fixed)
  2. Confirm Jira deployment type
    Check if running Jira Server, Jira Data Center, or Jira Software Data Center by reviewing the license or administration console
    Affected if Any of these deployment types are running and version falls within affected ranges in step 1
  3. Verify UserPickerBrowser.jspa endpoint exists
    Access the URL pattern: https://<your-jira-base>/secure/UserPickerBrowser.jspa or check for its presence in the web application files under <jira-install>/atlassian-jira/secure/
    Affected if The endpoint is present and accessible (this page is included by default in affected versions)

If Jira version is 7.x below 7.13.9 OR 8.0.0 through 8.4.1, and UserPickerBrowser.jspa is accessible, the environment is vulnerable to the DoS condition described in CVE-2019-20413.
