CVE-2026-71865

Orval: Import-time RCE via query parameter name -> computed-property-key injection in the zod cli

State: Published
Severity: 9.3 Critical
Published: Aug 19, 2026
Updated: Aug 21, 2026
Reserved: Aug 7, 2026

Description

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.
