CVE-2019-25211: Gin mishandles a wildcard at the end of an origin string
(updated )
parseWildcardRules in Gin-Gonic CORS middleware before 1.6.0 mishandles a wildcard at the end of an origin string, e.g., https://example.community/* is allowed when the intention is that only https://example.com/* should be allowed, and http://localhost.example.com/* is allowed when the intention is that only http://localhost/* should be allowed.
