Description · from the CVE record

orval versions before 8.29.0 contain a code injection vulnerability in the @orval/hono generator that fails to escape OpenAPI path values in single-quoted route literals. Attackers can craft an OpenAPI document with an apostrophe in a static path segment to inject arbitrary JavaScript code that executes when the generated TypeScript module is imported.
