The archive extraction utilities used by Logstash do not properly validate file paths within compressed archives. An attacker who can serve a specially crafted archive to Logstash through a compromised or attacker-controlled update endpoint can write arbitrary files to the host filesystem with the privileges of the Logstash process. In certain configurations where automatic pipeline reloading is enabled, this can be escalated to remote code execution.", "title": "cveprojectv5 - https://www.cve.org/CVERecord?id=CVE-2026-33466" }, { "category": "other", "text": "0.00847", "title": "EPSS" }, { "category": "other", "text": "6.6", "title": "NCSC Score" }, { "category": "other", "text": "The value of the most recent EPSS score, VENDOR FIX as product remediation category, There is product data available from source Certbundde, There is product data available from source Oracle", "title": "NCSC Score top increasing factors" }, { "category": "other", "text": "Is related to (a version of) an uncommon product, Is related to a product by vendor Open Source", "title": "NCSC Score top decreasing factors" } ], "product_status": { "known_affected": [ "CSAFPID-6016086", "CSAFPID-6016087", "CSAFPID-6016088", "CSAFPID-6212260", "CSAFPID-6212261", "CSAFPID-6212262", "CSAFPID-6014281", "CSAFPID-6222648", "CSAFPID-6222649", "CSAFPID-6222650", "CSAFPID-8656118", "CSAFPID-8656117", "CSAFPID-8656116", "CSAFPID-9763631", "CSAFPID-1844415", "CSAFPID-1844417", "CSAFPID-2726967", "CSAFPID-8879366", "CSAFPID-9010902" ] }, "references": [ { "category": "external", "summary": "Source - osv", "url": "https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/GIT%2FCVE-2026-33466.json?alt=media" }, { "category": "external", "summary": "Source - first", "url": "https://api.first.org/data/v1/epss" }, { "category": "external", "summary": "Source - nvd", "url": "https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-33466" }, { "category": "external", "summary": "Source - certbundde", "url": "https://wid.cert-bund.de/.well-known/csaf/white/2026/wid-sec-w-2026-1025.json" }, { "category": "external", "summary": "Source - ncscclear", "url": "https://vulnerabilities.ncsc.nl/manual/CVE-2026-33466" }, { "category": "external", "summary": "Source - cveprojectv5", "url": "https://www.cve.org/CVERecord?id=CVE-2026-33466" }, { "category": "external", "summary": "Source - osv", "url": "https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/Bitnami%2FBIT-logstash-2026-33466.json?alt=media" }, { "category": "external", "summary": "Source - oracle", "url": "https://www.oracle.com/a/tech/docs/security-alerts/cpuoct2026csaf.json" }, { "category": "external", "summary": "Source - ncscclear", "url": "https://advisories.ncsc.nl/advisory?id=NCSC-2026-0439" }, { "category": "external", "summary": "Source - certbundde", "url": "https://wid.cert-bund.de/.well-known/csaf/white/2026/wid-sec-w-2026-4082.json" }, { "category": "external", "summary": "Reference - certbundde; cveprojectv5; nvd; osv", "url": "https://discuss.elastic.co/t/logstash-8-19-14-9-2-8-9-3-3-security-update-esa-2026-29/385816" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://wid.cert-bund.de/.well-known/csaf/white/2026/wid-sec-w-2026-1025.json" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2026-1025" }, { "category": "external", "summary": "Reference - osv", "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-33466" }, { "category": "external", "summary": "Reference - osv", "url": "https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33466.json" }, { "category": "external", "summary": "Reference - oracle", "url": "https://www.oracle.com/security-alerts/cpuoct2026.html" }, { "category": "external", "summary": "Reference - oracle", "url": "https://www.oracle.com/docs/tech/security-alerts/cpuoct2026csaf.json" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://wid.cert-bund.de/.well-known/csaf/white/2026/wid-sec-w-2026-4082.json" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2026-4082" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://www.oracle.com/security-alerts/cpuoct2026.html#AppendixPS" } ], "remediations": [ { "category": "vendor_fix", "details": "Oracle customers with valid support contracts", "product_ids": [ "CSAFPID-9763631" ], "url": "https://support.oracle.com/support/?documentId=CPU418" } ], "scores": [ { "cvss_v3": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL" }, "products": [ "CSAFPID-1844415", "CSAFPID-1844417", "CSAFPID-2726967", "CSAFPID-6014281", "CSAFPID-6016086", "CSAFPID-6016087", "CSAFPID-6016088", "CSAFPID-6212260", "CSAFPID-6212261", "CSAFPID-6212262", "CSAFPID-6222648", "CSAFPID-6222649", "CSAFPID-6222650", "CSAFPID-8656116", "CSAFPID-8656117", "CSAFPID-8656118", "CSAFPID-8879366", "CSAFPID-9010902", "CSAFPID-9763631" ] } ], "title": "CVE-2026-33466" } ] }
