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.","categories":["Unclassified"],"product":"UTMStack","vendor":"UTMStack","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-82044","source_modified_at":"2026-10-05T17:13:42.524Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"UTMStack","vendor":"UTMStack","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"11.2.16"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-82044","source_modified_at":"2026-10-05T17:13:42.524Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"UTMStack","ecosystem":null},"version":"11.2.16","basis":"first unaffected version stated in the CVE record"}],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00256,"percentile":0.16308,"score_date":"2026-10-23"},"published_at":"2026-10-02T20:20:47.694Z","modified_at":"2026-10-05T17:13:42.524Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-82044","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T17:13:42.524Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-82044","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","tags":["patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/utmstack-server-side-request-forgery-via-downloadpdf","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-05T17:12:36.497623Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T17:13:42.524Z","content_hash":"54bb65a4a94ef052893439b7a0819fde7fcd707b422cd7ba1548e718baf7900c"}}
