CVE-2026-54666
swagger-typescript-api vulnerable to code injection via unescaped OpenAPI path strings in generated method bodies
CVSS Score
8.3
EPSS Score
0.0%
EPSS Percentile
0th
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.
