These files would then be available over the TechDocs backend API.\n\nThis vulnerability is mitigated by the fact that an attacker would need access to modify the `mkdocs.yml` in the documentation source code, and would also need access to the TechDocs backend API.\n\n### Patches\n\nThe vulnerability is patched in the `0.6.3` release of `@backstage/techdocs-common`.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in the [Backstage repository](https://github.com/backstage/backstage)\n* Visit our chat, linked to in [Backstage README](https://github.com/backstage/backstage)","published":"2021-06-03T22:15:07.873Z","modified":"2026-10-20T10:54:44.588888724Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@backstage/techdocs-common","fixedVersion":"0.6.3"}],"fix":{"url":"https://github.com/backstage/backstage/commit/8cefadca04cbf01d0394b0cb1983247e5f1d6208","label":"backstage/backstage@8cefadc"},"references":[{"type":"ADVISORY","url":"https://github.com/backstage/backstage/releases/tag/release-2021-05-27"},{"type":"ADVISORY","url":"https://github.com/backstage/backstage/security/advisories/GHSA-pgf8-28gg-vpr6"},{"type":"FIX","url":"https://github.com/backstage/backstage/commit/8cefadca04cbf01d0394b0cb1983247e5f1d6208"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32662"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-20T10:54:44.588888724Z"}}
