CVE-2026-54666: Acacode Swagger-TypeScript-API

High severity, CVSS 8.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Acacode Swagger-TypeScript-API: before 13.12.2 (fixed in 13.12.2)
