CVE-2026-72716
CriticalCVSS 9.3Summary
Orval (prior to 8.21.0) generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. A ${...} expression or backtick in a query parameter default is emitted into a module-level template literal without safe encoding, allowing attacker-controlled JavaScript to be evaluated when the generated zod schema module is imported, resulting in code execution in the developer, CI, test, or application environment.
Risk Assessment
An attacker can execute arbitrary code in the environment where the generated module is imported, potentially leading to system compromise.
Recommendation
Update Orval to version 8.21.0 or later, which includes the fix.
Original NVD description (English source)
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a ${...} expression or backtick in a query parameter default is emitted into a module-level template literal emitted by zod schema generation without safe encoding. This permits attacker-controlled JavaScript to be evaluated when the generated zod schema module is imported, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/zod/src/index.ts function formatDefaultValue. This issue is fixed in version 8.21.0.
