Description
swagger-typescript-api generates API clients for Fetch or Axios from an OpenAPI Specification. Prior to 13.12.2, src/schema-parser/base-schema-parsers/enum.ts passes components.schemas.*.enum[i] values to Ts.StringValue in src/configuration.ts without escaping before templates/base/enum-data-contract.ejs renders TypeScript enum declarations, allowing an attacker-controlled OpenAPI spec to inject code that executes when the generated module is imported. This issue is fixed in version 13.12.2.
