{"id":"CVE-2025-55285","aliases":["GHSA-3x3q-ghcp-whf7"],"url":"https://o3.security/vulnerability/CVE-2025-55285","summary":"@backstage/plugin-scaffolder-backend Template Secret Leakage in Logs in Scaffolder When Using `fetch:template`","details":"@backstage/plugin-scaffolder-backend is the backend for the default Backstage software templates. Prior to version 2.1.1, duplicate logging of the input values in the fetch:template action in the Scaffolder meant that some of the secrets were not properly redacted. If ${{ secrets.x }} is not passed through to fetch:template there is no impact. This issue has been resolved in 2.1.1 of the scaffolder-backend plugin. A workaround for this issue involves Template Authors removing the use of ${{ secrets }} being used as an argument to fetch:template.","published":"2025-08-15T17:10:26.735Z","modified":"2026-08-12T03:51:35.004117002Z","cvss":{"score":2.6,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-backend","fixedVersion":"2.1.1"}],"fix":{"url":"https://github.com/backstage/backstage/commit/c371f6fe12371de31dca537510e6653e287cdc2e","label":"backstage/backstage@c371f6f"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55285.json"},{"type":"ADVISORY","url":"https://github.com/backstage/backstage/security/advisories/GHSA-3x3q-ghcp-whf7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55285"},{"type":"FIX","url":"https://github.com/backstage/backstage/commit/c371f6fe12371de31dca537510e6653e287cdc2e"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.004117002Z"}}
