CVE-2026-71866

Name of the Vulnerable Software and Affected Versions Orval versions 8.19.0 through 8.20.x

Description Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. A double quote in a schema property name is emitted into the generated zod.object({...}) schema without safe encoding. This allows attacker-controlled JavaScript to be evaluated when the generated zod schema module is imported, leading to code execution in the developer, CI, test, or application environment. The issue resides in packages/zod/src/index.ts and the zod object-key generation process.

Recommendations Update to version 8.21.0.
