Is this vulnerability remotely exploitable?

It can be, if an attacker can remotely influence the OpenAPI/Swagger specification that Orval consumes—for example, through a shared spec platform, a compromised upstream repository, or a service that imports external specs into your pipeline. Once the malicious spec is processed, the resulting generated code may execute attacker-controlled logic.

What level of access does an attacker need to exploit this?

An attacker needs the ability to create, modify, or substitute the OpenAPI/Swagger specification used by Orval. Direct access to your build system is not required if you automatically trust and process external or shared specifications.

What is the safest general fix pattern?

The most robust fix is to ensure that all spec-derived fields used in code generation—especially descriptive metadata like `x-enumDescriptions`—are properly escaped or sanitized before being embedded into generated code, and to restructure generation so that untrusted data cannot alter the code's control flow or syntax.
