Potential fix for https://github.com/raid-ppcoe/open-design/security/code-scanning/244
General fix: validate runtime type of untrusted HTTP body before using it in downstream logic, and reject unsupported/body-shape variants instead of coercing everything.
Best fix here (without changing intended functionality for normal API clients):
In
apps/daemon/src/routes/vela.ts, tightenvelaProxyRequestBodyto only acceptBuffer,string, plain JSON objects, andnull/undefined; explicitly reject arrays and other non-plain objects by returning an invalid marker. Then inproxyAmrApiRequest, handle invalid bodies with400and stop processing. This prevents type confusion from parameter tampering while preserving existing behavior for valid request bodies.Needed changes:
velaProxyRequestBodyreturn type to includeundefinedas “invalid”.proxyAmrApiRequestafter body extraction.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
