CVE-2022-32205 [MEDIUM] CWE-770 CVE-2022-32205: A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl a A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to av

CVE-2022-32206 [MEDIUM] CWE-770 CVE-2022-32206: curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be c curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a

CVE-2022-27782 [HIGH] CWE-840 CVE-2022-27782: libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been ch libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match che

CVE-2022-27778 [HIGH] CWE-706 CVE-2022-27778: A use of incorrectly resolved name vulnerability fixed in 7.83.1 might remove the wrong file when `- A use of incorrectly resolved name vulnerability fixed in 7.83.1 might remove the wrong file when `--no-clobber` is used together with `--remove-on-error`.

CVE-2022-27780 [HIGH] CWE-177 CVE-2022-27780: The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host na The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flaw

CVE-2022-27779 [MEDIUM] CWE-201 CVE-2022-27779: libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided wi libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast preven

CVE-2022-27774 [MEDIUM] CWE-522 CVE-2022-27774: An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with authentication could leak credentials to other services that exist on different protocols or port numbers.

CVE-2022-30115 [MEDIUM] CWE-325 CVE-2022-30115: Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure cle Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the

CVE-2021-22926 [HIGH] CWE-840 CVE-2021-22926: libcurl-using applications can ask for a specific client certificate to be used in a transfer. This 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 opt

CVE-2021-22922 [MEDIUM] CWE-840 CVE-2021-22922: When curl is instructed to download content using the metalink feature, thecontents is verified agai 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 o

CVE-2021-22925 [MEDIUM] CWE-200 CVE-2021-22925: curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely 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 revea

CVE-2021-22923 [MEDIUM] CWE-319 CVE-2021-22923: When curl is instructed to get content using the metalink feature, and a user name and password are 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.
