https://notcve.org/view.php?id=CVE-2021-22946
15 Sep 2021 — A user can tell curl >= 7.20.0 and <= 7.78.0 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` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitiv... • http://seclists.org/fulldisclosure/2022/Mar/29 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •

05 Aug 2021 — libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users ... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-295: Improper Certificate Validation CWE-840: Business Logic Errors •
