OpenSearch has issue with fine-grained access control of indices backing data streams

Impact

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 indices that back data streams potentially leading to incorrect access authorization. This issue can only be triggered by authenticated users authorized to read those data streams which are backed by the impacted indexes. Additionally, existing privileged users cannot access random indexes within these clusters; they can only access indexes to which they have already been granted permission.

Patches

OpenSearch 1.3.7 and 2.4.0 contain a fix for this issue.

Workarounds

There is no recommended work around.
