Description Marian Rehak 2021-09-10 14:11:33 UTC 
A user can tell curl to **require** a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or
`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` with libcurl). This requirement can be bypassed. This flaw would then make curl silently continue its operations **without TLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.
