{"id":"CVE-2026-54663","aliases":["GHSA-x36r-4347-pm5x"],"url":"https://o3.security/vulnerability/CVE-2026-54663","summary":"swagger-typescript-api vulnerable to Server-Side Request Forgery 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 warmUpRemoteSchemasCache resolves external $ref URLs and fetchRemoteSchemaDocument uses isHttpUrl to fetch any http or https target without private IP, redirect, DNS rebinding, or same-origin validation, allowing an attacker-controlled OpenAPI spec to make the generator issue requests to internal or link-local services. This issue is fixed in version 13.12.2.","published":"2026-07-29T14:28:33.360Z","modified":"2026-08-12T03:51:44.006443624Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"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-2026-54663.json"},{"type":"ADVISORY","url":"https://github.com/acacode/swagger-typescript-api/security/advisories/GHSA-x36r-4347-pm5x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54663"},{"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":"2026-08-12T03:51:44.006443624Z"}}
