CVE-2026-62682
CriticalCVSS 9.3Summary
Orval before 8.21.0 unsafely encodes unescaped backticks in servers[0].url in generated request URL template literals when output.baseUrl.getBaseUrlFromSpecification is enabled, 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 servers[0].url is emitted into request URL template literals generated when output.baseUrl.getBaseUrlFromSpecification is enabled without safe encoding. This permits attacker-controlled JavaScript to be evaluated when a generated request or URL-builder 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 function getFullRoute. This issue is fixed in version 8.21.0.
