Is this vulnerability remotely exploitable?

It can be, if an attacker can cause your Orval setup to consume a malicious OpenAPI specification remotely (for example, via a URL, a compromised dependency, or a pull request feeding a spec into your CI). Once the malicious spec is used to generate code and that code is built or run, the injected payload can execute.

What level of access does an attacker need?

The attacker needs the ability to influence or replace the OpenAPI/Swagger specification used by Orval's MCP server generator. This could be through direct repository access, control over a referenced remote spec, or any mechanism that lets them modify the spec before generation.

What is the safest general fix pattern?

The safest approach is to ensure that all specification fields, including `summary`, are treated as untrusted input and are properly escaped or encoded before being inserted into generated code. Code generation should rely on robust templating with context-aware escaping, avoiding raw string concatenation of spec content into executable sections.
