This affects deployments with `permission.enabled: true` and an Elasticsearch or OpenSearch search backend.\n\n### Patches\n\n- Upgrade `@backstage/plugin-search-backend` to 2.1.6\n- Upgrade `@backstage/plugin-search-backend-module-elasticsearch` to 1.8.7\n\n### Workarounds\n\nIf you are unable to upgrade immediately:\n\n- Temporarily modify permission policies to use `CONDITIONAL` decisions with per-result filtering rather than blanket `DENY` for search document types\n- 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.","state":0,"publishedAt":"2026-10-07T18:02:52+00:00","modifiedAt":"2026-10-07T18:15:11.183398+00:00","affected":[{"ecosystem":"npm","name":"@backstage/plugin-search-backend","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.1.6"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"@backstage/plugin-search-backend-module-elasticsearch","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.8.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-9325-vq29-gp3v","https://nvd.nist.gov/vuln/detail/CVE-2026-106562","https://github.com/backstage/backstage/commit/2d5d3e77d630455d6d48cfa8f31fd3c126fd6f29","https://github.com/backstage/backstage","https://github.com/backstage/backstage/releases/tag/v1.54.1"],"sourceUrl":"https://github.com/advisories/GHSA-9325-vq29-gp3v","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-9325-vq29-gp3v","identifiers":["GHSA-9325-vq29-gp3v","CVE-2026-106562"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
