https://notcve.org/view.php?id=CVE-2021-22923
05 Aug 2021 — When curl is instructed to get content using the metalink feature, and a user name and password are used to download the metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl will download or try to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened.

CVE-2021-22926 – Gentoo Linux Security Advisory 202212-01
https://notcve.org/view.php?id=CVE-2021-22926
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 •

CVE-2021-22925 – curl: Incorrect fix for CVE-2021-22898 TELNET stack contents disclosure
https://notcve.org/view.php?id=CVE-2021-22925
22 Jul 2021 — curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly when... • http://seclists.org/fulldisclosure/2021/Sep/39 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •

CVE-2021-22897
https://notcve.org/view.php?id=CVE-2021-22897
11 Jun 2021 — curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transpo... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-668: Exposure of Resource to Wrong Sphere CWE-840: Business Logic Errors •

09 Dec 2020 — A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions.
