| CVE-2025-0725 | 2 Haxx, Netapp | 11 Curl, Libcurl, Hci Baseboard Management Controller and 8 more | 2025-06-12 | N/A | 7.3 HIGH |
| When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the `CURLOPT_ACCEPT_ENCODING` option, **using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow would make libcurl perform a buffer overflow. | |||||

| 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 | 5 Debian, Fedoraproject, Haxx and 2 more | 14 Debian Linux, Fedora, Libcurl and 11 more | 2025-06-09 | N/A | 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. | |||||

| 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 | 7 Debian, Fedoraproject, Haxx and 4 more | 53 Debian Linux, Fedora, Libcurl and 50 more | 2025-06-09 | 4.3 MEDIUM | 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 | 8 Broadcom, Debian, Fedoraproject and 5 more | 11 Fabric Operating System, Debian Linux, Fedora and 8 more | 2025-06-09 | 4.3 MEDIUM | 3.7 LOW |
| 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. | |||||

| 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 | 5 Apple, Fedoraproject, Haxx and 2 more | 13 Macos, Fedora, Curl and 10 more | 2025-05-07 | N/A | 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 | 5 Apple, Debian, Haxx and 2 more | 18 Macos, Debian Linux, Curl and 15 more | 2025-05-05 | N/A | 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 | 6 Apple, Debian, Fedoraproject and 3 more | 19 Macos, Debian Linux, Fedora and 16 more | 2025-05-05 | 4.3 MEDIUM | 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 | 6 Debian, Fedoraproject, Haxx and 3 more | 30 Debian Linux, Fedora, Curl and 27 more | 2025-05-05 | 4.3 MEDIUM | 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. | |||||
| CVE-2022-32205 | 7 Apple, Debian, Fedoraproject and 4 more | 29 Macos, Debian Linux, Fedora and 26 more | 2025-05-05 | 4.3 MEDIUM | 4.3 MEDIUM |
| 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 avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method. | |||||
| CVE-2022-32207 | 6 Apple, Debian, Fedoraproject and 3 more | 19 Macos, Debian Linux, Fedora and 16 more | 2025-04-23 | 7.5 HIGH | 9.8 CRITICAL |
| When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. | |||||
| CVE-2023-27534 | 5 Broadcom, Fedoraproject, Haxx and 2 more | 13 Brocade Fabric Operating System Firmware, Fedora, Curl and 10 more | 2025-04-23 | N/A | 8.8 HIGH |
| A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user. | |||||
| CVE-2017-1000101 | 1 Haxx | 1 Curl | 2025-04-20 | 4.3 MEDIUM | 6.5 MEDIUM |
| curl supports "globbing" of URLs, in which a user can pass a numerical range to have the tool iterate over those numbers to do a sequence of transfers. In the globbing function that parses the numerical range, there was an omission that made curl read a byte beyond the end of the URL if given a carefully crafted, or just wrongly written, URL. The URL is stored in a heap based buffer, so it could then be made to wrongly read something else instead of crashing. An example of a URL that triggers the flaw would be `http://ur%20[0-60000000000000000000`. | |||||
| CVE-2017-1000099 | 1 Haxx | 1 Libcurl | 2025-04-20 | 4.3 MEDIUM | 6.5 MEDIUM |
| When asking to get a file from a file:// URL, libcurl provides a feature that outputs meta-data about the file using HTTP-like headers. The code doing this would send the wrong buffer to the user (stdout or the application's provide callback), which could lead to other private data from the heap to get inadvertently displayed. The wrong buffer was an uninitialized memory area allocated on the heap and if it turned out to not contain any zero byte, it would continue and display the data following that buffer in memory. | |||||
| CVE-2017-7407 | 1 Haxx | 1 Curl | 2025-04-20 | 2.1 LOW | 2.4 LOW |
| The ourWriteOut function in tool_writeout.c in curl 7.53.1 might allow physically proximate attackers to obtain sensitive information from process memory in opportunistic circumstances by reading a workstation screen during use of a --write-out argument ending in a '%' character, which leads to a heap-based buffer over-read. | |||||
| CVE-2017-8817 | 2 Debian, Haxx | 3 Debian Linux, Curl, Libcurl | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| The FTP wildcard function in curl and libcurl before 7.57.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a string that ends with an '[' character. | |||||
| CVE-2017-8816 | 2 Debian, Haxx | 3 Debian Linux, Curl, Libcurl | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact via vectors involving long user and password fields. | |||||
| CVE-2017-1000100 | 1 Haxx | 1 Libcurl | 2025-04-20 | 4.3 MEDIUM | 6.5 MEDIUM |
| When doing a TFTP transfer and curl/libcurl is given a URL that contains a very long file name (longer than about 515 bytes), the file name is truncated to fit within the buffer boundaries, but the buffer size is still wrongly updated to use the untruncated length. This too large value is then used in the sendto() call, making curl attempt to send more data than what is actually put into the buffer. The endto() function will then read beyond the end of the heap based buffer. A malicious HTTP(S) server could redirect a vulnerable libcurl-using client to a crafted TFTP URL (if the client hasn't restricted which protocols it allows redirects to) and trick it to send private memory contents to a remote server over UDP. Limit curl's redirect protocols with --proto-redir and libcurl's with CURLOPT_REDIR_PROTOCOLS. | |||||
