Improper Authorization of Index Containing Sensitive Information


Severity High
Score 7.5/10


OpenSearch Security is a plugin for OpenSearch that offers encryption, authentication and authorization. Versions and of the security plugin are affected by an information disclosure vulnerability. 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. OpenSearch 2.2.0, which is compatible with OpenSearch Security, contains the fix for this issue. There is no recommended work around.
