  "description": "The curl URL parser wrongly accepts percent-encoded URL separators like \u0027/\u0027when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like \u0060http://example.com%2F127.0.0.1/\u0060, would be allowed bythe parser and get transposed into \u0060http://example.com/127.0.0.1/\u0060. This flawcan be used to circumvent filters, checks and more.",
