CVE-2026-71865
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications.
Impact
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a double quote in a query parameter name is emitted into the generated request-validation zod.object({...}) schema 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 and query request-validation generation. This issue is fixed in version 8.21.0.
