Field-level security issue with .keyword fields in OpenSearch

Quick fix

GHSA-v3cg-7r9h-r2g6 — org.opensearch.plugin:opensearch-security: upgrade to the fixed version with the command below.

# pom.xml: bump <version>1.3.8</version> for org.opensearch.plugin:opensearch-security

Details

### Advisory title: Field-level security issue with .keyword fields

### Affected versions: OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1

### Patched versions: OpenSearch 1.3.8 and 2.5.0

### Impact: There is an issue in the implementation of field-level security (FLS) and field masking where rules written to explicitly exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword fields.

This issue is only present for authenticated users with read access to the indexes containing the restricted fields.

### Workaround: FLS rules that use explicit exclusions can be written to grant explicit access instead. Policies authored in this way are not subject to this issue.

### Patches: OpenSearch versions 1.3.8 and 2.5.0 contain a fix for this issue.

### For more information: If you have any questions or comments about this advisory, please contact AWS/Amazon Security via our issue reporting page (https://aws.amazon.com/security/vulnerability-reporting/) or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com).
