How to fix?

Upgrade curl to version 7.83.1 or higher.

Overview

curl is a command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP. libcurl offers a myriad of powerful features.

Affected versions of this package are vulnerable to Inappropriate Encoding for Output Context due to the URL parser which wrongly accepts percent-encoded URL separators like / when decoding the hostname part of a URL, making it a different URL using the wrong hostname when it is later retrieved.
