CVE-2026-71864
CriticalCVSS 9.3Summary
Orval before 8.21.0 unsafely encodes double quotes in header parameter names in generated request-validation zod.object({...}) schemas, allowing malicious JavaScript execution when the module is imported.
Risk Assessment
An attacker can inject code that executes in development, CI, test, or production environments, potentially leading to system compromise.
Recommendation
Update Orval to version 8.21.0 or later, which includes the fix for safe encoding.
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 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.
