| summary: Insecure wildcard CORS policy in github.com/rs/cors |
| description: |- |
| The CORS handler actively converts a wildcard CORS policy into reflecting an |
| arbitrary Origin header value, which is incompatible with the CORS security |
| design, and could lead to CORS misconfiguration security problems. |
