CVE-2018-20744: github.com/gofiber/fiber/v2 vulnerable to Origin Validation Error
(updated )
The Olivier Poitrey Go CORS handler through 1.3.0 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.
