| CVE-2025-14017 | 1 Haxx | 1 Curl | 2026-06-17 | N/A | 6.3 MEDIUM |
| When doing multi-threaded LDAPS transfers (LDAP over TLS) with libcurl, changing TLS options in one thread would inadvertently change them globally and therefore possibly also affect other concurrently setup transfers. Disabling certificate verification for a specific transfer could unintentionally disable the feature for other threads as well. | |||||
| CVE-2025-13034 | 1 Haxx | 1 Curl | 2026-06-17 | N/A | 5.9 MEDIUM |
| When using `CURLOPT_PINNEDPUBLICKEY` option with libcurl or `--pinnedpubkey` with the curl tool,curl should check the public key of the server certificate to verify the peer. This check was skipped in a certain condition that would then make curl allow the connection without performing the proper check, thus not noticing a possible impostor. To skip this check, the connection had to be done with QUIC with ngtcp2 built to use GnuTLS and the user had to explicitly disable the standard certificate verification. | |||||
| CVE-2025-11563 | 2 Curl, Haxx | 2 Wcurl, Curl | 2026-06-17 | N/A | 4.6 MEDIUM |
| URLs containing percent-encoded slashes (`/` or `\`) can trick wcurl into saving the output file outside of the current directory without the user explicitly asking for it. This flaw only affects the wcurl command line tool. | |||||
| CVE-2025-10966 | 1 Haxx | 1 Curl | 2026-06-17 | N/A | 4.3 MEDIUM |
| curl's code for managing SSH connections when SFTP was done using the wolfSSH powered backend was flawed and missed host verification mechanisms. This prevents curl from detecting MITM attackers and more. | |||||
| CVE-2025-10148 | 1 Haxx | 1 Curl | 2026-06-17 | N/A | 5.3 MEDIUM |
| curl's websocket code did not update the 32 bit mask pattern for each new outgoing frame as the specification says. Instead it used a fixed mask that persisted and was used throughout the entire connection. A predictable mask pattern allows for a malicious server to induce traffic between the two communicating parties that could be interpreted by an involved proxy (configured or transparent) as genuine, real, HTTP traffic with content and thereby poison its cache. That cached poisoned content could then be served to all users of that proxy. | |||||
| CVE-2025-0725 | 3 Haxx, Netapp, Zlib | 12 Curl, Libcurl, Hci Baseboard Management Controller and 9 more | 2026-06-17 | 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. | |||||
| CVE-2025-0665 | 2 Haxx, Netapp | 13 Curl, Bootstrap Os, H300s and 10 more | 2026-06-17 | N/A | 7.0 HIGH |
| libcurl would wrongly close the same eventfd file descriptor twice when taking down a connection channel after having completed a threaded name resolve. | |||||
| CVE-2025-0167 | 2 Haxx, Netapp | 25 Curl, Bootstrap Os, Element Software and 22 more | 2026-06-17 | N/A | 3.4 LOW |
| When asked to use a `.netrc` file for credentials **and** to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests itself if the netrc file has a `default` entry that omits both login and password. A rare circumstance. | |||||
| CVE-2024-9681 | 1 Haxx | 1 Curl | 2026-06-17 | N/A | 6.5 MEDIUM |
| When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than otherwise intended. This affects curl using applications that enable HSTS and use URLs with the insecure `HTTP://` scheme and perform transfers with hosts like `x.example.com` as well as `example.com` where the first host is a subdomain of the second host. (The HSTS cache either needs to have been populated manually or there needs to have been previous HTTPS accesses done as the cache needs to have entries for the domains involved to trigger this problem.) When `x.example.com` responds with `Strict-Transport-Security:` headers, this bug can make the subdomain's expiry timeout *bleed over* and get set for the parent domain `example.com` in curl's HSTS cache. The result of a triggered bug is that HTTP accesses to `example.com` get converted to HTTPS for a different period of time than what was asked for by the origin server. If `example.com` for example stops supporting HTTPS at its expiry time, curl might then fail to access `http://example.com` until the (wrongly set) timeout expires. This bug can also expire the parent's entry *earlier*, thus making curl inadvertently switch back to insecure HTTP earlier than otherwise intended. | |||||
| CVE-2024-8096 | 3 Debian, Haxx, Netapp | 15 Debian Linux, Curl, Active Iq Unified Manager and 12 more | 2026-06-17 | N/A | 6.5 MEDIUM |
| When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate. | |||||
| CVE-2024-7264 | 1 Haxx | 1 Libcurl | 2026-06-17 | N/A | 6.5 MEDIUM |
| libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application when [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used. | |||||
| CVE-2024-6874 | 1 Haxx | 1 Libcurl | 2026-06-17 | N/A | 4.3 MEDIUM |
| libcurl's URL API function [curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode conversions, to and from IDN. Asking to convert a name that is exactly 256 bytes, libcurl ends up reading outside of a stack based buffer when built to use the *macidn* IDN backend. The conversion function then fills up the provided buffer exactly - but does not null terminate the string. This flaw can lead to stack contents accidently getting returned as part of the converted string. | |||||
| CVE-2024-6197 | 1 Haxx | 1 Libcurl | 2026-06-17 | N/A | 7.5 HIGH |
| libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. Itcan detect an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte localstack buffer. Most modern malloc implementations detect this error and immediately abort. Some however accept the input pointer and add that memory to its list of available chunks. This leads to the overwriting of nearby stack memory. The content of the overwrite is decided by the `free()` implementation; likely to be memory pointers and a set of flags. The most likely outcome of exploting this flaw is a crash, although it cannot be ruled out that more serious results can be had in special circumstances. | |||||
| CVE-2024-32928 | 2 Google, Haxx | 3 Nest Mini, Nest Mini Firmware, Libcurl | 2026-06-17 | N/A | 5.9 MEDIUM |
| The libcurl CURLOPT_SSL_VERIFYPEER option was disabled on a subset of requests made by Nest production devices which enabled a potential man-in-the-middle attack on requests to Google cloud services by any host the traffic was routed through. | |||||
| CVE-2024-2466 | 3 Apple, Haxx, Netapp | 12 Macos, Curl, Bootstrap Os and 9 more | 2026-06-17 | N/A | 6.5 MEDIUM |
| libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate check. This affects all uses of TLS protocols (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc). | |||||
| CVE-2024-2398 | 4 Apple, Fedoraproject, Haxx and 1 more | 22 Macos, Fedora, Curl and 19 more | 2026-06-17 | N/A | 8.6 HIGH |
| When an application tells libcurl it wants to allow HTTP/2 server push, and the amount of received headers for the push surpasses the maximum allowed limit (1000), libcurl aborts the server push. When aborting, libcurl inadvertently does not free all the previously allocated headers and instead leaks the memory. Further, this error condition fails silently and is therefore not easily detected by an application. | |||||
| CVE-2024-2379 | 3 Apple, Haxx, Netapp | 20 Macos, Curl, Active Iq Unified Manager and 17 more | 2026-06-17 | N/A | 6.3 MEDIUM |
| libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the verification and returns OK, thus ignoring any certificate problems. | |||||
| CVE-2024-2004 | 4 Apple, Fedoraproject, Haxx and 1 more | 15 Macos, Fedora, Curl and 12 more | 2026-06-17 | N/A | 3.5 LOW |
| When a protocol selection parameter option disables all protocols without adding any then the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols. The below command would perform a request to curl.se with a plaintext protocol which has been explicitly disabled. curl --proto -all,-http http://curl.se The flaw is only present if the set of selected protocols disables the entire set of available protocols, in itself a command with no practical use and therefore unlikely to be encountered in real situations. The curl security team has thus assessed this to be low severity bug. | |||||
| CVE-2024-11053 | 2 Haxx, Netapp | 19 Curl, Bootstrap Os, H300s and 16 more | 2026-06-17 | N/A | 3.4 LOW |
| When asked to both use a `.netrc` file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests itself if the netrc file has an entry that matches the redirect target hostname but the entry either omits just the password or omits both login and password. | |||||
| CVE-2024-0853 | 1 Haxx | 1 Curl | 2026-06-17 | N/A | 5.3 MEDIUM |
| curl inadvertently kept the SSL session ID for connections in its cache even when the verify status (*OCSP stapling*) test failed. A subsequent transfer to the same hostname could then succeed if the session ID cache was still fresh, which then skipped the verify status check. | |||||
