- Issue
- I am reporting a code injection vulnerability in Orval’s mock generation pipeline affecting @orval/mock in both the 7.x and 8.x series. This issue is related in impact to the previously reported enum x-enumDescriptions (https://github.com/advisories/GHSA-h526-wf6g-67jv), but it affects a different code path in the faker-based mock generator rather than @orval/core. The vulnerability allows 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. I have confirmed that this occurs on orval@7.19.0 and orval@8.0.2 with mock: true, and that the generated mocks contain executable payloads such as…
Recommended action: Upgrade to 8.0.3 or 7.20.0 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
