| CVE-2014-8150 | 3 Canonical, Debian, Haxx | 3 Ubuntu Linux, Debian Linux, Libcurl | 2026-05-06 | 4.3 MEDIUM | N/A |
| CRLF injection vulnerability in libcurl 6.0 through 7.x before 7.40.0, when using an HTTP proxy, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in a URL. | |||||
| CVE-2015-3153 | 5 Apple, Canonical, Debian and 2 more | 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more | 2026-05-06 | 5.0 MEDIUM | N/A |
| The default configuration for cURL and libcurl before 7.42.1 sends custom HTTP headers to both the proxy and destination server, which might allow remote proxy servers to obtain sensitive information by reading the header contents. | |||||
| CVE-2016-5420 | 3 Debian, Haxx, Opensuse | 3 Debian Linux, Libcurl, Leap | 2026-05-06 | 5.0 MEDIUM | 7.5 HIGH |
| curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate. | |||||
| CVE-2015-3236 | 1 Haxx | 2 Curl, Libcurl | 2026-05-06 | 5.0 MEDIUM | N/A |
| cURL and libcurl 7.40.0 through 7.42.1 send the HTTP Basic authentication credentials for a previous connection when reusing a reset (curl_easy_reset) connection handle to send a request to the same host name, which allows remote attackers to obtain sensitive information via unspecified vectors. | |||||
| CVE-2013-4545 | 1 Haxx | 2 Curl, Libcurl | 2026-04-29 | 4.3 MEDIUM | N/A |
| cURL and libcurl 7.18.0 through 7.32.0, when built with OpenSSL, disables the certificate CN and SAN name field verification (CURLOPT_SSL_VERIFYHOST) when the digital signature verification (CURLOPT_SSL_VERIFYPEER) is disabled, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. | |||||
| CVE-2013-0249 | 2 Canonical, Haxx | 3 Ubuntu Linux, Curl, Libcurl | 2026-04-29 | 7.5 HIGH | N/A |
| Stack-based buffer overflow in the Curl_sasl_create_digest_md5_message function in lib/curl_sasl.c in curl and libcurl 7.26.0 through 7.28.1, when negotiating SASL DIGEST-MD5 authentication, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in the realm parameter in a (1) POP3, (2) SMTP or (3) IMAP message. | |||||
| CVE-2011-3389 | 9 Canonical, Debian, Google and 6 more | 17 Ubuntu Linux, Debian Linux, Chrome and 14 more | 2026-04-29 | 4.3 MEDIUM | N/A |
| The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack. | |||||
| CVE-2013-1944 | 2 Canonical, Haxx | 3 Ubuntu Linux, Curl, Libcurl | 2026-04-29 | 5.0 MEDIUM | N/A |
| The tailMatch function in cookie.c in cURL and libcurl before 7.30.0 does not properly match the path domain when sending cookies, which allows remote attackers to steal cookies via a matching suffix in the domain of a URL. | |||||
| CVE-2013-2174 | 4 Canonical, Haxx, Opensuse and 1 more | 5 Ubuntu Linux, Curl, Libcurl and 2 more | 2026-04-29 | 6.8 MEDIUM | N/A |
| Heap-based buffer overflow in the curl_easy_unescape function in lib/escape.c in cURL and libcurl 7.7 through 7.30.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string ending in a "%" (percent) character. | |||||
| CVE-2013-6422 | 3 Canonical, Debian, Haxx | 3 Ubuntu Linux, Debian Linux, Libcurl | 2026-04-29 | 4.0 MEDIUM | N/A |
| The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification (CURLOPT_SSL_VERIFYPEER), also disables the CURLOPT_SSL_VERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks. | |||||
| CVE-2014-0015 | 1 Haxx | 2 Curl, Libcurl | 2026-04-29 | 4.0 MEDIUM | N/A |
| cURL and libcurl 7.10.6 through 7.34.0, when more than one authentication method is enabled, re-uses NTLM connections, which might allow context-dependent attackers to authenticate as other users via a request. | |||||
| CVE-2011-2192 | 5 Apple, Canonical, Debian and 2 more | 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more | 2026-04-29 | 4.3 MEDIUM | N/A |
| The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl and other products, always performs credential delegation during GSSAPI authentication, which allows remote servers to impersonate clients via GSSAPI requests. | |||||
| CVE-2021-22925 | 7 Apple, Fedoraproject, Haxx and 4 more | 27 Mac Os X, Macos, Fedora and 24 more | 2026-04-16 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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 whenparsing the string provided by the application. | |||||
| CVE-2022-27782 | 3 Debian, Haxx, Splunk | 3 Debian Linux, Curl, Universal Forwarder | 2026-04-16 | 5.0 MEDIUM | 7.5 HIGH |
| 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 checks, making themmatch too easily. | |||||
| CVE-2022-27781 | 4 Debian, Haxx, Netapp and 1 more | 16 Debian Linux, Curl, Clustered Data Ontap and 13 more | 2026-04-16 | 5.0 MEDIUM | 7.5 HIGH |
| libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation. | |||||
| CVE-2022-22576 | 5 Brocade, Debian, Haxx and 2 more | 17 Fabric Operating System, Debian Linux, Curl and 14 more | 2026-04-16 | 5.5 MEDIUM | 8.1 HIGH |
| An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). | |||||
| CVE-2021-22947 | 8 Apple, Debian, Fedoraproject and 5 more | 34 Macos, Debian Linux, Fedora and 31 more | 2026-04-16 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe 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. | |||||
| CVE-2021-22946 | 8 Apple, Debian, Fedoraproject and 5 more | 37 Macos, Debian Linux, Fedora and 34 more | 2026-04-16 | 5.0 MEDIUM | 7.5 HIGH |
| 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 sensitive data in clear text over the network. | |||||
| CVE-2021-22922 | 6 Fedoraproject, Haxx, Netapp and 3 more | 23 Fedora, Curl, Cloud Backup and 20 more | 2026-04-16 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk. | |||||
| CVE-2020-8285 | 9 Apple, Debian, Fedoraproject and 6 more | 30 Mac Os X, Macos, Debian Linux and 27 more | 2026-04-16 | 5.0 MEDIUM | 7.5 HIGH |
| curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. | |||||
