Name of the Vulnerable Software and Affected Versions
Orval versions prior to 8.21.0
Description
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. A double quote in a header parameter name is emitted into the generated request-validation
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 header request-validation generation.Recommendations
Update to version 8.21.0.
