CVE-2014-2522 2 Haxx, Microsoft 3 Curl, Libcurl, Windows 2026-06-17 4.0 MEDIUM N/A
curl and libcurl 7.27.0 through 7.35.0, when running on Windows and using the SChannel/Winssl TLS backend, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate when accessing a URL that uses a numerical IP address, which allows man-in-the-middle attackers to spoof servers via an arbitrary valid certificate.
CVE-2014-0139 1 Haxx 2 Curl, Libcurl 2026-06-17 5.8 MEDIUM N/A
cURL and libcurl 7.1 before 7.36.0, when using the OpenSSL, axtls, qsossl or gskit libraries for TLS, recognize a wildcard IP address in the subject's Common Name (CN) field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
CVE-2014-0138 2 Debian, Haxx 3 Debian Linux, Curl, Libcurl 2026-06-17 6.4 MEDIUM N/A
The default configuration in cURL and libcurl 7.10.6 before 7.36.0 re-uses (1) SCP, (2) SFTP, (3) POP3, (4) POP3S, (5) IMAP, (6) IMAPS, (7) SMTP, (8) SMTPS, (9) LDAP, and (10) LDAPS connections, which might allow context-dependent attackers to connect as other users via a request, a similar issue to CVE-2014-0015.
CVE-2014-0015 1 Haxx 2 Curl, Libcurl 2026-06-17 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-2013-4545 1 Haxx 2 Curl, Libcurl 2026-06-16 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-2013-2174 4 Canonical, Haxx, Opensuse and 1 more 5 Ubuntu Linux, Curl, Libcurl and 2 more 2026-06-16 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-2013-1944 2 Canonical, Haxx 3 Ubuntu Linux, Curl, Libcurl 2026-06-16 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-2013-0249 2 Canonical, Haxx 3 Ubuntu Linux, Curl, Libcurl 2026-06-16 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-2005-0490 1 Haxx 2 Curl, Libcurl 2026-06-16 5.1 MEDIUM 8.8 HIGH
Multiple stack-based buffer overflows in libcURL and cURL 7.12.1, and possibly other versions, allow remote malicious web servers to execute arbitrary code via base64 encoded replies that exceed the intended buffer lengths when decoded, which is not properly handled by (1) the Curl_input_ntlm function in http_ntlm.c during NTLM authentication or (2) the Curl_krb_kauth and krb4_auth functions in krb4.c during Kerberos authentication.
CVE-2003-1605 1 Haxx 1 Curl 2026-06-16 5.0 MEDIUM 7.5 HIGH
curl 7.x before 7.10.7 sends CONNECT proxy credentials to the remote server.
