Summary

Backstage has incorrect authorization in search engine permission filtering

Details

Impact

An authenticated Backstage user subject to a DENY policy for search document types could receive search results they were not authorized to view. This affects deployments with permission.enabled: true and an Elasticsearch or OpenSearch search backend.

Patches

Upgrade @backstage/plugin-search-backend to 2.1.6
Upgrade @backstage/plugin-search-backend-module-elasticsearch to 1.8.7

Workarounds

If you are unable to upgrade immediately:

Temporarily modify permission policies to use CONDITIONAL decisions with per-result filtering rather than blanket DENY for search document types
Restrict Elasticsearch/OpenSearch index access at the cluster level so that the search service account can only reach expected Backstage indices, limiting the blast radius if the authorization bypass is triggered.
