## 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.

Affected packages and fixed versions:
- org.opensearch.plugin:opensearch-security (Maven): affected from 1.0.0; fixed in 2.19.4.0
- org.opensearch.plugin:opensearch-security (Maven): affected from 1.0.0; fixed in 2.19.4.0
- org.opensearch.plugin:opensearch-security (Maven): affected from 3.0.0; fixed in 3.2.0.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
