CVE-2024-8096 4 Curl, Debian, Haxx and 1 more 16 Curl, Debian Linux, Curl and 13 more 2025-07-30 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-2025-0167 3 Curl, Haxx, Netapp 26 Curl, Curl, Bootstrap Os and 23 more 2025-07-30 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-2025-5025 2 Curl, Haxx 2 Curl, Curl 2025-07-30 4.8 Medium
libcurl supports *pinning* of the server certificate public key for HTTPS transfers. Due to an omission, this check is not performed when connecting with QUIC for HTTP/3, when the TLS backend is wolfSSL. Documentation says the option works with wolfSSL, failing to specify that it does not for QUIC and HTTP/3. Since pinning makes the transfer succeed if the pin is fine, users could unwittingly connect to an impostor server without noticing.
CVE-2025-5399 2 Curl, Haxx 3 Curl, Libcurl, Curl 2025-07-30 7.5 High
Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet which makes libcurl get trapped in an endless busy-loop. There is no other way for the application to escape or exit this loop other than killing the thread/process. This might be used to DoS libcurl-using application.
CVE-2025-4947 2 Curl, Haxx 2 Curl, Curl 2025-06-26 6.5 Medium
libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks.
CVE-2012-0036 1 Curl 2 Curl, Libcurl 2025-04-11 N/A
curl and libcurl 7.2x before 7.24.0 do not properly consider special characters during extraction of a pathname from a URL, which allows remote attackers to conduct data-injection attacks via a crafted URL, as demonstrated by a CRLF injection attack on the (1) IMAP, (2) POP3, or (3) SMTP protocol.
CVE-2010-3842 1 Curl 1 Curl 2025-04-11 N/A
Absolute path traversal vulnerability in curl 7.20.0 through 7.21.1, when the --remote-header-name or -J option is used, allows remote servers to create or overwrite arbitrary files by using \ (backslash) as a separator of path components within the Content-disposition HTTP header.
CVE-2024-6197 2 Curl, Haxx 2 Curl, Libcurl 2025-02-13 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.
