Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a single quote in a schema property name is emitted into single-quoted object keys in generated MSW mock factories without safe encoding. This permits attacker-controlled JavaScript to be evaluated when the generated mock factory is called by tests or an MSW handler, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/core/src/getters/keys.ts function getKey and MSW mock generation. This issue is fixed in version 8.21.0.

CVE-2026-71865 is a critical code injection vulnerability in orval-labs' orval software prior to version 8.21.0. The issue arises because a double quote in a query parameter name is emitted into the generated zod schema without safe encoding, allowing attacker-controlled JavaScript to be executed when the schema module is imported. This can lead to code execution in developer, CI, test, or application environments. The vulnerability affects the code in packages/zod/src/index.ts and the query request-validation generation. The issue is fixed in version 8.21.0.
