CVE-2026-62681: CWE-94: Improper Control of Generation of Code ('Code Injection') in orval-labs orval
Description
CVE-2026-62681 is a critical code injection vulnerability in orval versions prior to 8.21.0. The issue arises because unescaped backticks in OpenAPI paths are directly embedded into JavaScript template literals used for generating request URLs in clients like axios, fetch, react-query, and SWR. This flaw allows attacker-controlled JavaScript code to be executed in environments where the generated code runs, such as developer machines, CI pipelines, test environments, or applications. The vulnerability is fixed in version 8.21.0.

Technical Analysis
Orval is a tool that generates type-safe JavaScript clients from OpenAPI and Swagger specifications. Before version 8.21.0, it improperly handles backticks in OpenAPI paths by embedding them unescaped into template literals for URL construction. This improper control of code generation (CWE-94) enables injection and execution of arbitrary JavaScript code when the generated request or query functions are invoked. The affected source code includes packages/core/src/getters/route.ts and related route generation consumers. The vulnerability has a CVSS 4.0 score of 9.3, indicating critical severity. The issue is resolved in orval 8.21.0.
Potential Impact
An attacker who can control the OpenAPI path input can inject JavaScript code that will be executed in the context of the developer, CI, test, or application environment where the generated client code runs. This can lead to arbitrary code execution, potentially compromising the environment and any sensitive data or processes running there.
Mitigation Recommendations
Upgrade orval to version 8.21.0 or later, where this vulnerability is fixed. No additional mitigation is required if the upgrade is applied. Patch status is confirmed fixed in 8.21.0.
