{"id":"CVE-2026-54661","aliases":["GHSA-38c3-wv3c-v3xj"],"url":"https://o3.security/vulnerability/CVE-2026-54661","summary":"swagger-typescript-api vulnerable to code injection via unescaped `servers[0].url` in axios http-client template","details":"swagger-typescript-api generates API clients for Fetch or Axios from an OpenAPI Specification. Prior to 13.12.2, templates/base/http-clients/axios-http-client.ejs interpolates servers[0].url from src/code-gen-process.ts into the HttpClient constructor without escaping, allowing an attacker-controlled OpenAPI spec to inject code that executes when new HttpClient() or new Api() is constructed. This issue is fixed in version 13.12.2.","published":"2026-07-29T14:30:29.903Z","modified":"2026-08-12T03:51:40.803988323Z","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":0.0027,"percentile":0.18862,"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-2026-54661.json"},{"type":"ADVISORY","url":"https://github.com/acacode/swagger-typescript-api/security/advisories/GHSA-38c3-wv3c-v3xj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54661"},{"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":"2026-08-12T03:51:40.803988323Z"}}
