    Backstage has incorrect authorization in search engine permission filtering

    CVE-2026-106562 · GHSA-9325-vq29-gp3v

    Affected
    • npm @backstage/plugin-search-backend < 2.1.6
    Fixed in
    2.1.6· Vendor fix available
    Issue
    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.

    Recommended action: Upgrade to 2.1.6 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
