Prior to versions 1.3.10 and 2.7.0, there is an issue with the implementation of fine-grained access control rules (document-level security, field-level security and field masking) where they are not correctly applied to the queries during extremely rare race conditions potentially leading to incorrect access authorization. For this issue to be triggered, two concurrent requests need to land on the same instance exactly when query cache eviction happens, once every four hours. OpenSearch 1.3.10 and 2.7.0 contain a fix for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-863"],"references":["https://github.com/opensearch-project/security/security/advisories/GHSA-g8xc-6mf7-h28h","https://github.com/opensearch-project/security/security/advisories/GHSA-g8xc-6mf7-h28h"],"products":["amazon:opensearch","amazon:opensearch_security"],"source":"nvd","synced_at":"2026-10-19T21:38:18.424950729+00:00"},"epss":{"cve":"CVE-2023-31141","score":0.0046,"percentile":0.39907,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-g8xc-6mf7-h28h","url":"https://osv.dev/vulnerability/GHSA-g8xc-6mf7-h28h","summary":"OpenSearch issue with fine-grained access control during extremely rare race conditions","modified":"2024-02-16T08:11:19.036510Z","packages":[{"ecosystem":"Maven","name":"org.opensearch.plugin:opensearch-security","purl":"pkg:maven/org.opensearch.plugin/opensearch-security","ranges":[">=1.0.0 <1.3.10.0"],"fixed":["1.3.10.0"]},{"ecosystem":"Maven","name":"org.opensearch.plugin:opensearch-security","purl":"pkg:maven/org.opensearch.plugin/opensearch-security","ranges":[">=2.0.0 <2.7.0.0"],"fixed":["2.7.0.0"]}]}],"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).
