CVE-2026-54666 is a high-severity vulnerability in swagger-typescript-api prior to version 13.12.2. The issue arises because OpenAPI path keys are passed into JavaScript template literals without proper escaping, allowing attacker-controlled input containing ${...} to be executed when the generated API client method is called. This improper neutralization of special elements leads to potential code injection. The vulnerability is fixed in version 13.12.2.

CVE-2026-54664 is a high severity code injection vulnerability in the swagger-typescript-api tool prior to version 13.12.2. The vulnerability arises because enum values from an OpenAPI specification are passed without proper escaping to template rendering code, allowing attacker-controlled input to inject executable code into generated TypeScript modules. This code executes when the generated module is imported. The issue is fixed in version 13.12.2.

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.

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.

swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/code-gen-process.ts createApiConfig copies servers[0].url into apiConfig.baseUrl, and templates/base/http-clients/fetch-http-client.ejs interpolates apiConfig.baseUrl into the generated HttpClient baseUrl field without escaping, allowing an attacker-controlled OpenAPI spec to inject TypeScript static field code that executes when the generated fetch client module is imported. This issue is fixed in version 13.12.2.

A vulnerability in swagger-typescript-api prior to version 13.12.2 allows exposure of sensitive bearer tokens. The issue occurs because the authorization token is forwarded to every URL fetched when resolving external references in OpenAPI specifications. This can lead to an attacker-controlled OpenAPI spec exfiltrating the developer or CI bearer token to a cross-origin endpoint. The vulnerability is fixed in version 13.12.2.
