{"id":"CVE-2026-54660","aliases":["GHSA-h754-fxp7-88wx"],"url":"https://o3.security/vulnerability/CVE-2026-54660","summary":"swagger-typescript-api vulnerable to authorization-token exfiltration via spec `$ref`","details":"swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/resolved-swagger-schema.ts getRemoteRequestHeaders forwards --authorizationToken to every URL fetched by fetchRemoteSchemaDocument while warmUpRemoteSchemasCache resolves external $ref URLs, allowing an attacker-controlled OpenAPI spec to exfiltrate the developer or CI bearer token to a cross-origin endpoint. This issue is fixed in version 13.12.2.","published":"2026-07-29T14:21:34.295Z","modified":"2026-08-12T03:51:23.728564305Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},"epss":{"score":0.00243,"percentile":0.15628,"asOf":"2026-09-12"},"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-2026-54660.json"},{"type":"ADVISORY","url":"https://github.com/acacode/swagger-typescript-api/security/advisories/GHSA-h754-fxp7-88wx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54660"},{"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":"2026-08-12T03:51:23.728564305Z"}}
