{"id":"CVE-2026-54666","aliases":["GHSA-w284-33mx-6g9v"],"url":"https://o3.security/vulnerability/CVE-2026-54666","summary":"swagger-typescript-api vulnerable to code injection via unescaped OpenAPI path strings in generated method bodies","details":"swagger-typescript-api generates API clients for Fetch or Axios from an OpenAPI Specification. Prior to 13.12.2, src/schema-routes/schema-routes.ts passes OpenAPI path keys through parseRouteName to templates/default/procedure-call.ejs and templates/modular/procedure-call.ejs without escaping JavaScript template literal interpolation, allowing an attacker-controlled path containing ${...} to execute when the generated method is called. This issue is fixed in version 13.12.2.","published":"2026-07-29T14:34:48.668Z","modified":"2026-08-12T03:51:11.664130471Z","cvss":{"score":8.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":{"score":0.00286,"percentile":0.20689,"asOf":"2026-09-02"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"swagger-typescript-api","fixedVersion":"13.12.2"}],"fix":{"url":"https://github.com/acacode/swagger-typescript-api/commit/306d59acb8ffbb00f953f807b97234b21f51d9de","label":"acacode/swagger-typescript-api@306d59a"},"references":[{"type":"WEB","url":"https://github.com/acacode/swagger-typescript-api/releases/tag/v13.12.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54666.json"},{"type":"ADVISORY","url":"https://github.com/acacode/swagger-typescript-api/security/advisories/GHSA-w284-33mx-6g9v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54666"},{"type":"FIX","url":"https://github.com/acacode/swagger-typescript-api/commit/306d59acb8ffbb00f953f807b97234b21f51d9de"},{"type":"FIX","url":"https://github.com/acacode/swagger-typescript-api/pull/1779"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.664130471Z"}}
