Vulnerability from fkie_nvd - Published: 2026-01-23 00:15 - Updated: 2026-01-23 00:15
Severity ?
Summary
Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Versions
7.19.0 and below and 8.0.0-rc.0 through 8.0.2 allow untrusted OpenAPI specifications to inject arbitrary TypeScript/JavaScript into generated mock files via the const keyword on schema properties. These const values are interpolated into the mock scalar generator (getMockScalar in packages/mock/src/faker/getters/scalar.ts) without proper escaping or type-safe serialization, which results in attacker-controlled code being emitted into both interface definitions and faker/MSW handlers. The vulnerability is similar in impact to the previously reported enum x-enumDescriptions (GHSA-h526-wf6g-67jv), but it affects a different code path in the faker-based mock generator rather than @orval/core. The issue has been fixed in versions 7.20.0 and 8.0.3.
