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.","aliases":["CVE-2026-106461"],"modified":"2026-10-07T18:15:13.179064809Z","published":"2026-10-07T17:58:55Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-10-07T17:58:55Z","nvd_published_at":"2026-10-06T21:17:16Z","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/backstage/backstage/commit/0253c50673f2832b0b1e9f73348186434e7bd09e"},{"type":"PACKAGE","url":"https://github.com/backstage/backstage"},{"type":"WEB","url":"https://github.com/backstage/backstage/releases/tag/v1.54.6"}],"affected":[{"package":{"name":"@backstage/plugin-scaffolder-backend","ecosystem":"npm","purl":"pkg:npm/%40backstage/plugin-scaffolder-backend"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.1.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-7hfw-grcm-cqm6/GHSA-7hfw-grcm-cqm6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
