CVE-2026-82044

HighCVSS 7.7
Published: Translated: NVD NIST

Summary

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.

Risk Assessment

This can lead to exposure of sensitive internal data, such as cloud metadata or OpenSearch cluster data, potentially enabling further attacks.

Recommendation

Upgrade UTMStack to version 11.2.16 or later and validate URL parameters in the downloadPdf method.
