CVE-2026-54666 Details
Description
swagger-typescript-api generates API clients for Fetch or Axios from an OpenAPI Specification. Prior to 13.12.2, src/schema-routes/schema-routes.ts passes OpenAPI path keys through parseRouteName to templates/default/procedure-call.ejs and templates/modular/procedure-call.ejs without escaping JavaScript template literal interpolation, allowing an attacker-controlled path containing ${...} to execute when the generated method is called. This issue is fixed in version 13.12.2.
A code injection vulnerability has been identified in the Swagger TypeScript API client generator, specifically in versions prior to 13.12.2. The issue arises in the 'schema-routes' processing file, where OpenAPI path keys are passed to the procedure call templates without proper escaping. This oversight allows an attacker to inject executable JavaScript into the generated API client methods. The vulnerability can be exploited by crafting a malicious OpenAPI specification that includes unescaped path strings or enum values, which are then executed with the full privileges of the importing process when the generated methods are called.
Users can update to Swagger TypeScript API version 13.12.2 or later, where this vulnerability has been fixed.
