CVE-2023-27533 5 Fedoraproject, Haxx, Netapp and 2 more 15 Fedora, Curl, Active Iq Unified Manager and 12 more 2026-02-13 9.8 Critical
A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system.
CVE-2023-23915 4 Haxx, Netapp, Redhat and 1 more 13 Curl, Active Iq Unified Manager, Clustered Data Ontap and 10 more 2026-02-13 6.5 Medium
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS.
CVE-2022-43551 5 Fedoraproject, Haxx, Netapp and 2 more 8 Fedora, Curl, Active Iq Unified Manager and 5 more 2026-02-13 7.5 High
A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypassed if the host name in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop (U+002E) `.`. Then in a subsequent request, it does not detect the HSTS state and makes a clear text transfer. Because it would store the info IDN encoded but look for it IDN decoded.
CVE-2022-42916 5 Apple, Fedoraproject, Haxx and 2 more 5 Macos, Fedora, Curl and 2 more 2026-02-13 7.5 High
In curl before 7.86.0, the HSTS check could be bypassed to trick it into staying with HTTP. Using its HSTS support, curl can be instructed to use HTTPS directly (instead of using an insecure cleartext HTTP step) even when HTTP is provided in the URL. This mechanism could be bypassed if the host name in the given URL uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion, e.g., using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.). The earliest affected version is 7.77.0 2021-05-26.
CVE-2022-35737 4 Netapp, Redhat, Splunk and 1 more 5 Ontap Select Deploy Administration Utility, Enterprise Linux, Rhel Eus and 2 more 2026-02-13 7.5 High
SQLite 1.0.12 through 3.39.x before 3.39.2 sometimes allows an array-bounds overflow if billions of bytes are used in a string argument to a C API.
CVE-2022-32221 6 Apple, Debian, Haxx and 3 more 16 Macos, Debian Linux, Curl and 13 more 2026-02-13 9.8 Critical
When doing HTTP(S) transfers, libcurl might 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. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST.
CVE-2025-20387 2 Microsoft, Splunk 4 Windows, Splunk, Splunk Enterprise and 1 more 2025-12-05 8 High
In Splunk Universal Forwarder for Windows versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, a new installation of or an upgrade to an affected version can result in incorrect permissions assignment in the Universal Forwarder for Windows Installation directory. This lets non-administrator users on the machine access the directory and all its contents.
CVE-2022-36227 5 Debian, Fedoraproject, Libarchive and 2 more 6 Debian Linux, Fedora, Libarchive and 3 more 2025-11-03 9.8 Critical
In libarchive before 3.6.2, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference. NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: "In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution."
CVE-2021-36976 4 Apple, Fedoraproject, Libarchive and 1 more 7 Ipados, Iphone Os, Macos and 4 more 2025-11-03 6.5 Medium
libarchive 3.4.1 through 3.5.1 has a use-after-free in copy_string (called from do_uncompress_block and process_block).
CVE-2025-20298 2 Microsoft, Splunk 2 Windows, Universal Forwarder 2025-08-04 8 High
In Universal Forwarder for Windows versions below 9.4.2, 9.3.4, 9.2.6, and 9.1.9, a new installation of or an upgrade to an affected version can result in incorrect permissions assignment in the Universal Forwarder for Windows Installation directory (by default, C:\Program Files\SplunkUniversalForwarder). This lets non-administrator users on the machine access the directory and all its contents.
CVE-2023-27538 7 Broadcom, Debian, Fedoraproject and 4 more 16 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 13 more 2025-06-09 7.7 High
An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection.
CVE-2023-27535 6 Debian, Fedoraproject, Haxx and 3 more 16 Debian Linux, Fedora, Libcurl and 13 more 2025-06-09 5.9 Medium
An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too easily. This could lead to libcurl using the wrong credentials when performing a transfer, potentially allowing unauthorized access to sensitive information.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2025-06-09 9.1 Critical
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*.
CVE-2021-22924 8 Debian, Fedoraproject, Haxx and 5 more 55 Debian Linux, Fedora, Libcurl and 52 more 2025-06-09 3.7 Low
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.
CVE-2021-22890 9 Broadcom, Debian, Fedoraproject and 6 more 12 Fabric Operating System, Debian Linux, Fedora and 9 more 2025-06-09 4.3 Medium
curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check.
CVE-2021-22876 9 Broadcom, Debian, Fedoraproject and 6 more 15 Fabric Operating System, Debian Linux, Fedora and 12 more 2025-06-09 5.3 Medium
curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
CVE-2022-42915 6 Apple, Fedoraproject, Haxx and 3 more 14 Macos, Fedora, Curl and 11 more 2025-05-07 8.1 High
curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0.
CVE-2022-35252 6 Apple, Debian, Haxx and 3 more 21 Macos, Debian Linux, Curl and 18 more 2025-05-05 3.7 Low
When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings.
CVE-2022-32208 7 Apple, Debian, Fedoraproject and 4 more 21 Macos, Debian Linux, Fedora and 18 more 2025-05-05 5.9 Medium
When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.
CVE-2022-32206 7 Debian, Fedoraproject, Haxx and 4 more 35 Debian Linux, Fedora, Curl and 32 more 2025-05-05 6.5 Medium
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 decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.
