CVE-2026-54660

HIGH CVSS 3.1: 7.4 EPSS 0.24%
Updated Jul 30, 2026
swagger-typescript-api
Parameter Value
CVSS 7.4 (HIGH)
Fixed In 13.12.2
Type CWE-200 (Information Exposure), CWE-201, CWE-918 (Server-Side Request Forgery (SSRF)), CWE-522 (Insufficiently Protected Credentials)
Vendor swagger-typescript-api
Public PoC No

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.
