Summary

Search permission filtering in @backstage/plugin-search-backend before 2.1.6 and @backstage/plugin-search-backend-module-elasticsearch before 1.8.7 can return documents that a DENY policy blocks (CWE-863). An authenticated user under such a policy can receive unauthorized search results when permission.enabled is true with an Elasticsearch or OpenSearch backend.

Description from the CNA

Backstage is an open framework for building developer portals. Prior to 2.1.6 in @backstage/plugin-search-backend and 1.8.7 in @backstage/plugin-search-backend-module-elasticsearch, search engine permission filtering could return documents denied by policy. An authenticated Backstage user subject to a DENY policy for search document types could receive unauthorized results in deployments with permission.enabled set to true and an Elasticsearch or OpenSearch backend. This issue is fixed in @backstage/plugin-search-backend 2.1.6 and @backstage/plugin-search-backend-module-elasticsearch 1.8.7.
