Summary
Orval: Import-time RCE via schema property name -> computed-property-key injection in the zod client
Details

Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. From version 8.19.0 until 8.21.0, a double quote in a schema property name is emitted into the generated 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 zod object-key generation. This issue is fixed in version 8.21.0.
