orval is vulnerable to Code Injection
86
High Risk
This Affects:
orvalTL;DR
Orval embeds untrusted OpenAPI values directly into generated TypeScript across the zod, effect, and hono generators, including numeric constraints emitted as bare expressions, default values converted into backtick templates, and raw path segments placed in single-quoted method chains. A crafted specification can break out of these contexts and inject arbitrary JavaScript that runs at module import time. This yields build-time code execution wherever the generated schemas or handlers are imported. The fix validates numeric constraints and escapes strings and defaults before interpolation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you generate zod, effect, or hono output from an untrusted or externally influenced OpenAPI document.
Background info
orval is vulnerable to Code Injection in versions 6.13.0 - 8.28.1.
How to fix this
