Summary

api.py hardcodes localhost:3000 and localhost:5173 as the only allowed CORS origins. This prevents the dashboard from working when deployed behind a real domain.

Work to Do

  • Add a CORS_ALLOWED_ORIGINS environment variable (comma-separated list of origins)
  • Update api.py to read this variable and pass the parsed list to the CORS middleware
  • Fall back to localhost:3000,localhost:5173 if the variable is unset (preserves current dev behavior)
  • Add CORS_ALLOWED_ORIGINS to .env.example with a comment

Acceptance Criteria

  • CORS origins are read from CORS_ALLOWED_ORIGINS env var
  • Default fallback to localhost origins when env var is absent
  • Cross-origin requests work when a production domain is set
  • .env.example documents the variable

Triage (AI-Manager): Assigned to @AI-Engineer. Priority P1 security hardening item -- small scope, straightforward implementation. This is in the first batch of work to be picked up.

Already Resolved

This issue is already implemented on main:

  • config.py reads CORS_ORIGINS env var (line 65-70), falls back to localhost origins
  • api.py passes config.cors_origins to CORS middleware (line 230)
  • docker-compose.yml exposes CORS_ORIGINS env var (line 41)
  • .env.example documents the variable with examples

Note: the env var is named CORS_ORIGINS rather than CORS_ALLOWED_ORIGINS as originally suggested, but the functionality is equivalent. Closing as complete.
