Stored task secrets are not included in the affected response, and no integrity or availability impact was identified.\n\n### Patches\n\nPatched in `@backstage/plugin-scaffolder-backend` version `4.1.0`\n\n### Workarounds\n\n- Restrict the scaffolder task-list endpoint at the ingress or authenticating proxy to users who are permitted to view all tasks.\n- Avoid placing sensitive values in template input parameters until the patched package is deployed.","published":"2026-10-06T20:25:32.100Z","modified":"2026-10-21T02:54:35.243500081Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-backend","fixedVersion":"4.1.0"}],"fix":{"url":"https://github.com/backstage/backstage/commit/0253c50673f2832b0b1e9f73348186434e7bd09e","label":"backstage/backstage@0253c50"},"references":[{"type":"WEB","url":"https://github.com/backstage/backstage/releases/tag/v1.54.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106461.json"},{"type":"ADVISORY","url":"https://github.com/backstage/backstage/security/advisories/GHSA-7hfw-grcm-cqm6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106461"},{"type":"FIX","url":"https://github.com/backstage/backstage/commit/0253c50673f2832b0b1e9f73348186434e7bd09e"},{"type":"PACKAGE","url":"https://github.com/backstage/backstage"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:54:35.243500081Z"}}
