Title
Orval MCP client is vulnerable to code injection via unsanitized x-enum-descriptions in enum generation
Summary
Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Versions 7.10.0 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 8.0.2 contains a fix for the issue.

CVE-2026-22785 (GCVE-0-2026-22785)

Vulnerability from cvelistv5 – Published: 2026-01-12 18:43 – Updated: 2026-01-12 18:56

Title
orval MCP client is vulnerable to a code injection attack.
Summary
orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Prior to 7.18.0, the MCP server generation logic relies on string manipulation that incorporates the summary field from the OpenAPI specification without proper validation or escaping. This allows an attacker to "break out" of the string literal and inject arbitrary code. This vulnerability is fixed in 7.18.0.
Severity ?
9.3 (Critical)
