The vulnerability allows a remote attacker to redirect the target client to an arbitrary site.
The vulnerability exists due to out-of-bounds read in the FTP wildcard function (CURLOPT_WILDCARDMATCH). A remote unauthenticated attacker can use a string that ends with an '[' character, trigger out-of-bounds read and cause the target connected libcurl client to be redirected.
