Impact
Requests to an OpenSearch cluster configured with advanced access control features (document level security (DLS), field level security (FLS), and/or field masking) will not be filtered when the query's search pattern matches an aliased index.
OpenSearch Dashboards creates an alias to .kibana by default, so filters with the index pattern of * to restrict access to documents or fields will not be applied.
This issue allows requests to access sensitive information when customer have acted to restrict access that specific information.
Patches
