{"id":"GHSA-x83w-23jp-g6pw","aliases":[],"url":"https://o3.security/vulnerability/GHSA-x83w-23jp-g6pw","summary":"OpenSearch Security plugin: DLS not applied on documents linked by has_child or has_parent relation","details":"### Description\n\nA flaw was identified in the OpenSearch Security plugin's document-level security (DLS) implementation. DLS restrictions were not correctly applied to search queries that use has_parent or has_child join relations. This could allow an authenticated user to access document contents that should have been restricted by DLS rules.\n\n### Impact\n\nAn authenticated user with access to an index containing parent/child join relations could bypass DLS restrictions on documents linked by those relations, potentially accessing restricted document contents. This only affects clusters that use both DLS and the `join` field type on the same index.\n\n### Patches\n\n This issue is fixed in OpenSearch `2.19.4` and `3.2.0`.\n\n### Workarounds\n\nAvoid using the `join` field type on indices that are subject to DLS rules.","published":"2026-05-07T00:08:34Z","modified":"2026-05-07T00:21:03.836489Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.opensearch.plugin:opensearch-security","fixedVersion":"2.19.4.0"},{"ecosystem":"Maven","name":"org.opensearch.plugin:opensearch-security","fixedVersion":"3.2.0.0"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/opensearch-project/security/security/advisories/GHSA-x83w-23jp-g6pw"},{"type":"PACKAGE","url":"https://github.com/opensearch-project/security"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-05-07T00:21:03.836489Z"}}
