## Overview

orval versions 8.14.0 through 8.28.1 contain a code injection vulnerability in the @orval/effect generator that converts OpenAPI schema defaults into template literals. Attackers can inject arbitrary JavaScript expressions via schema defaults containing ${...} syntax, which are executed at module scope when the generated code is built or imported.
