Prior to 3.1.5, authenticated users with permission to execute scaffolder dry-runs can gain access to server-configured environment secrets through the dry-run API response. Secrets are properly redacted in log output but not in all parts of the response payload. Deployments that have configured scaffolder.defaultEnvironment.secrets are affected. This is patched in @backstage/plugin-scaffolder-backend version 3.1.5.","published":"2026-03-12T18:38:57.156Z","modified":"2026-08-07T11:31:33.669534243Z","cvss":{"score":4.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-backend","fixedVersion":"3.1.5"}],"fix":{"url":"https://github.com/backstage/backstage/commit/3b62dd2d6bf7623ebd23e4b5a6dceb209f98dfce","label":"backstage/backstage@3b62dd2"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32237.json"},{"type":"ADVISORY","url":"https://github.com/backstage/backstage/security/advisories/GHSA-8wq8-6859-qx77"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32237"},{"type":"FIX","url":"https://github.com/backstage/backstage/commit/3b62dd2d6bf7623ebd23e4b5a6dceb209f98dfce"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:33.669534243Z"}}
