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
An issue in OpenKnowledgeMaps Headstart v7 allows a remote attacker to escalate privileges via the url parameter of the getPDF.php component

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

OpenKnowledgeMaps Headstart v7 contains a privilege escalation vulnerability in the getPDF.php component. The url parameter is not properly validated, allowing a remote attacker to potentially manipulate the parameter to escalate privileges.

MitigationImplement strict input validation and sanitization on the url parameter in getPDF.php. Use allowlists for permitted values and validate that the URL follows expected patterns before processing.

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. Locate the getPDF.php file
    Search the web server document root for the file getPDF.php - common paths include /include/, /lib/, or /api/ directories within the Headstart installation
    Affected if The file getPDF.php exists in the application directory structure
  2. Confirm Headstart version
    Check the installed version of OpenKnowledgeMaps Headstart by examining version files, composer.json, or the application metadata (often in a VERSION, package.json, or similar file in the root directory)
    Affected if The installed version is v7 or falls within the v7.x release line
  3. Verify url parameter is accessible
    Examine the getPDF.php file to confirm it accepts a 'url' parameter (look for $_GET['url'] or $_POST['url'] in the code)
    Affected if The getPDF.php script processes a 'url' parameter without documented input validation or allowlisting
  4. Test parameter manipulation
    Send a crafted request to getPDF.php with an arbitrary url parameter value (e.g., ?url=http://example.com) and observe if the application processes it without sanitization or rejection
    Affected if The url parameter accepts and processes values without validation or allowlist enforcement

A user is affected if they run OpenKnowledgeMaps Headstart v7 and the getPDF.php component is accessible with an unvalidated url parameter that can be manipulated for privilege escalation.
