CVE-2026-71864
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications.
Overview
CVE-2026-71864 is a known-severity vulnerability. It was published on August 19, 2026.
Technical 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 header 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 header request-validation generation. This issue is fixed in version 8.21.0.
