If a policy allowing external network access has been added to Elasticsearch's Java Security Manager then an attacker could send a specially crafted request capable of leaking content of local files on the Elasticsearch node. This could allow a user to access information that they should not have access to.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-611"],"references":["http://www.securityfocus.com/bid/106294","https://discuss.elastic.co/t/elastic-stack-6-5-2-security-update/159594","https://www.elastic.co/community/security","http://www.securityfocus.com/bid/106294","https://discuss.elastic.co/t/elastic-stack-6-5-2-security-update/159594"],"products":["elastic:elasticsearch"],"source":"nvd","synced_at":"2026-10-19T20:54:36.112582389+00:00"},"epss":{"cve":"CVE-2018-17247","score":0.01383,"percentile":0.72178,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-ccmr-qj26-845g","url":"https://osv.dev/vulnerability/GHSA-ccmr-qj26-845g","summary":"Improper Restriction of XML External Entity Reference in Elasticsearch","modified":"2023-11-08T04:00:03.960932Z","packages":[{"ecosystem":"Maven","name":"org.elasticsearch:elasticsearch","purl":"pkg:maven/org.elasticsearch/elasticsearch","ranges":[">=6.5.0 <6.5.2"],"fixed":["6.5.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
