DescriptionGitHub Advisory

Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Versions prior to 7.19.0 until 8.0.2 are vulnerable to arbitrary code execution in environments consuming generated clients. This issue is similar in nature to CVE-2026-22785, but affects a different code path in @orval/core that was not addressed by CVE-2026-22785's fix. The vulnerability allows untrusted OpenAPI specifications to inject arbitrary TypeScript/JavaScript code into generated clients via the x-enumDescriptions field, which is embedded without proper escaping in getEnumImplementation(). I have confirmed that the injection occurs during const enum generation and results in executable code within the generated schema files. Orval 7.19.0 and 8.0.2 contain a fix for the issue.

AnalysisAI

Orval, a TypeScript API client generator, has a command injection vulnerability that allows code execution through malicious OpenAPI specifications.

Technical ContextAI

Orval processes OpenAPI v3/Swagger v2 specifications to generate TypeScript clients, but fails to sanitize specification content (CWE-77), allowing injection of OS commands that execute during the code generation process.

RemediationAI

Update Orval to the patched version. Only generate code from trusted API specifications. Review generated code before execution.
