Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

orval-labs orval是orval-labs组织的一款服务器设备与网络产品。 orval-labs orval 8.21.0之前版本存在代码注入漏洞，该漏洞源于在enum默认值中的${...}表达式或反引号未经过安全编码就被输出到模块级模板字面量，可能导致导入生成的zod schema模块时执行攻击者控制的JavaScript，造成代码执行。

Vulnerability Title
Orval: Import-time RCE via enum-typed default -> zod module-level template literal
Source: CVE Program / CVE List V5
Vulnerability 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 an enum 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.
