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.","published":"2026-10-02T21:16:56.933","modified":"2026-10-02T21:16:56.933","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","label":"utmstack/UTMStack@4e7a727"},"references":[{"type":"WEB","url":"https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16"},{"type":"WEB","url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/utmstack-server-side-request-forgery-via-downloadpdf"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-02T21:16:56.933"}}
