Orval MCP client is vulnerable to code injection via unsanitized x-enum-descriptions in enum generation

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.

Orval 安全漏洞

Orval是Orval开源的一个接口开发工具。 Orval 7.10.0版本至8.0.2之前版本存在安全漏洞，该漏洞源于x-enumDescriptions字段未经适当转义嵌入，可能导致任意代码执行。
