63) Insufficient verification of data authenticity (CVE-ID: CVE-2021-22947)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists in the way libcurl handles the STARTTLS negotiation process. When curl connects to an IMAP, POP3, SMTP or FTP server to exchange data securely using STARTTLS to upgrade the connection to TLS level, the server can still respond and send back multiple responses before the TLS upgrade. Such multiple "pipelined" responses are cached by curl. curl would then upgrade to TLS but not flush the in-queue of cached responses and instead use and trust the responses it got before the TLS handshake as if they were authenticated.
Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.
Over POP3 and IMAP an attacker can inject fake response data.
64) Use-after-free (CVE-ID: CVE-2023-28319)

65) Improper Certificate Validation (CVE-ID: CVE-2021-22926)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to an error in the CURLOPT_SSLCERT option mixup with TLS library Secure Transport. A remote attacker can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake.
66) Cleartext transmission of sensitive information (CVE-ID: CVE-2021-22946)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error, related to incorrect enforcement of the --ssl-reqd option on the command line or CURLOPT_USE_SSL setting set to CURLUSESSL_CONTROL or CURLUSESSL_ALL with libcurl. A remote attacker with control over the IMAP, POP3 or FTP server can send a specially crafted but perfectly legitimate response to the libcurl client and force it silently to continue its operations without TLS encryption and transmit data in clear text over the network.
67) Incorrect Implementation of Authentication Algorithm (CVE-ID: CVE-2022-27782)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several TLS and SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure processing of compressed HTTP responses. A malicious server can send a specially crafted HTTP response to curl and perform a denial of service attack by forcing curl to spend enormous amounts of allocated heap memory, or trying to and returning out of memory errors.
70) Information disclosure (CVE-ID: CVE-2022-27776)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to curl can leak authentication or cookie header data during HTTP redirects to the same host but another port number. When asked to send custom headers or cookies in its HTTP requests, curl sends that set of headers only to the host which name is used in the initial URL, so that redirects to other hosts will make curl send the data to those. However, due to a flawed check, curl wrongly also sends that same set of headers to the hosts that are identical to the first one but use a different port number or URL scheme.
The vulnerability exists due to an incomplete fix for #VU10224 (CVE-2018-1000007).
71) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-23916)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to usage of uninitialized variable in code, responsible for processing TELNET requests when parsing NEW_ENV variables. A remote attacker can force the affected application to connect to a telnet server under attackers control and read up to 1800 bytes from the uninitialized memory on the libcurl client system.
78) Insufficiently protected credentials (CVE-ID: CVE-2021-22923)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to insufficiently protected credentials. A remote attacker can gain access to sensitive information on the target system.
79) Input validation error (CVE-ID: CVE-2022-35252)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an
HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.
80) Expected behavior violation (CVE-ID: CVE-2023-28322)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a logic error when sending HTTP POST and PUT requests using the same handle. The libcurl can erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously was used to issue a PUT request which used that callback. As a result, the application can misbehave and either send off the wrong data or use memory after free or similar in the second transfer.
81) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
