UTMStack < 11.2.16 Server-Side Request Forgery via downloadPdf

Type: advisorySource: Official CVE List1 source record

UTMStack before 11.2.16 contains a server-side request forgery vulnerability that allows authenticated attackers to make the server request arbitrary internal resources by supplying an unvalidated url parameter to the PdfService.downloadPdf() method exposed via GET /api/generate-pdf-report. Attackers can leverage this to force the web-pdf microservice to fetch internal backend endpoints, the OpenSearch cluster, or the cloud instance-metadata service, exposing sensitive internal data rendered into the returned PDF.
