CVE-2026-62681 PUBLISHED

Orval: RCE via OpenAPI path -> unescaped request-URL template literal (backtick breakout)

Assigner: GitHub_M
Reserved: 14.07.2026 Published: 19.08.2026 Updated: 19.08.2026

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.
