DATE CVE VULNERABILITY TITLE RISK
2021-09-29 CVE-2021-22946 Cleartext Transmission of Sensitive Information vulnerability in multiple products
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).

2021-09-29 CVE-2021-22947 Insufficient Verification of Data Authenticity vulnerability in multiple products
When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches.
4.3
2021-09-23 CVE-2021-22945 Double Free vulnerability in multiple products
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
5.8
2021-08-05 CVE-2021-22922 Improper Validation of Integrity Check Value vulnerability in multiple products
When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them.
4.3
2021-08-05 CVE-2021-22923 Insufficiently Protected Credentials vulnerability in multiple products
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.

2021-08-05 CVE-2021-22924 Use of Incorrectly-Resolved Name or Reference vulnerability in multiple products
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
4.3
2021-08-05 CVE-2021-22925 Use of Uninitialized Resource vulnerability in multiple products
curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl.

2021-06-11 CVE-2021-22897 Exposure of Resource to Wrong Sphere vulnerability in Haxx Curl
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.

2021-06-11 CVE-2021-22898 Missing Initialization of Resource vulnerability in multiple products
curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers.
