CVE-2026-71868: CWE-94: Improper Control of Generation of Code ('Code Injection') in orval-labs orval
Description
CVE-2026-71868 is a critical code injection vulnerability in orval-labs' orval tool prior to version 8.21.0. The vulnerability arises because unencoded ${...} expressions or backticks in enum default values are emitted directly into module-level template literals during zod schema generation, allowing attacker-controlled JavaScript code to be executed when the generated module is imported. This can lead to code execution in developer, CI, test, or application environments. The issue is fixed in version 8.21.0.

Technical Analysis
Orval is a tool that generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. In versions before 8.21.0, the function formatDefaultValue in packages/zod/src/index.ts improperly handles default enum values containing ${...} expressions or backticks by emitting them without safe encoding into module-level template literals. This flaw enables an attacker to inject and execute arbitrary JavaScript code when the generated zod schema module is imported. The vulnerability is classified as CWE-94 (Improper Control of Generation of Code) and CWE-1336. It has a CVSS 4.0 score of 9.3, indicating critical severity. The vulnerability is resolved in version 8.21.0.
Potential Impact
An attacker can execute arbitrary JavaScript code in the context of the developer, continuous integration, testing, or application environment by injecting malicious code into enum default values. This can lead to full code execution, potentially compromising the build or runtime environment where the generated schema module is imported.
Mitigation Recommendations
Upgrade orval to version 8.21.0 or later, where this vulnerability is fixed. No other mitigation is indicated or required as the fix addresses the root cause.
