The curl URL parser wrongly accepts percent-encoded URL separators like '/'when 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 http://example.com%2F127.0.0.1/
, would be allowed bythe parser and get transposed into http://example.com/127.0.0.1/
. This flawcan be used to circumvent filters, checks and more.
