What is GHSA-x83w-23jp-g6pw?
GHSA-x83w-23jp-g6pw is a vulnerability in org.opensearch.plugin:opensearch-security, published on 7 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Description
A 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.
Impact
An 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.
Patches
This issue is fixed in OpenSearch 2.19.4 and 3.2.0.
Workarounds
Avoid using the join field type on indices that are subject to DLS rules.
