CyberRota Analysis
AI-GeneratedOrval versions prior to 8.21.0 are vulnerable due to improper encoding of header parameter defaults, allowing attacker-controlled JavaScript to be executed upon importing the generated zod schema module. This critical vulnerability can lead to arbitrary code execution in various environments, including development and CI/CD pipelines. Developers and organizations utilizing Orval for generating TypeScript clients from OpenAPI specifications should prioritize upgrading to version 8.21.0 to mitigate this risk.

Original NVD Description
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a ${...} expression or backtick in a header parameter default is emitted into a module-level template literal emitted by zod schema generation 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 function formatDefaultValue. This issue is fixed in version 8.21.0.
