CVE-2026-62681
CriticalCVSS 9.3Summary
Orval before 8.21.0 unsafely encodes unescaped backticks in OpenAPI paths in generated request URL template literals for axios, fetch, react-query, and SWR clients, allowing malicious JavaScript execution when a generated function is called.
Risk Assessment
An attacker can inject code that executes in development, CI, test, or production environments, potentially leading to system compromise.
Recommendation
Update Orval to version 8.21.0 or later, which includes the fix for safe encoding.
Original NVD description (English source)
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, an unescaped backtick in an OpenAPI path is emitted into request URL template literals generated for axios, fetch, react-query, and SWR clients without safe encoding. This permits attacker-controlled JavaScript to be evaluated when a generated request, URL-builder, or query-key function is called, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/core/src/getters/route.ts and route generation consumers. This issue is fixed in version 8.21.0.
