A fix is available — apply it.

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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
