> DESCRIPTION

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 query 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 query request-validation generation. This issue is fixed in version 8.21.0.

> CWE DETAILED DESCRIPTIONS

CWE-94: Improper Control of Generation of Code ('Code Injection') - The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. | CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') - The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). | CWE-116: Improper Encoding or Escaping of Output - The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
