curl: CVE-2026-6276: stale custom cookie host causes cookie leak

Summary: libcurl keeps a stale data-state.aptr.cookiehost after a request that uses a custom Host: header. On later requests on the same easy handle, when no custom Host: is used, libcurl still reuses that stale value for outgoing cookie selection lib/http.c:2560-2563 and incoming Set-Cookie...

The vulnerability of the libcurl library in software tools for interacting with servers via cURL allows a hacker to induce a service failure.

The vulnerability of the libcurl library in software applications for interacting with servers via cURL is related to improper verification of certificate authenticity. Exploiting this vulnerability can allow an attacker to cause service failures...

curl: CVE-2026-6253: proxy credentials leak over redirect-to proxy

Summary: When libcurl follows a redirect and the new URL causes proxy re-selection, proxy credentials learned from the originally selected proxy URL can remain in per-transfer state and be reused for the next proxy. In the validated case, a redirect from http:// to https:// switches selection fro...

curl: Argument Injection via curl Short-Flag Grouping

This report details how the curl -os command facilitates an Argument Injection vulnerability in applications that wrap the curl command-line tool. The specific command curl -os /etc/passwd --url http://example.com demonstrates a subtle but dangerous behavior. Because -s silent follows -o output,...

The vulnerability of the software for interacting with servers via cURL lies in the ability to utilize memory after it is released, allowing a hacker to cause a service failure.

The vulnerability of the software for interacting with servers via cURL is related to the possibility of using memory after it is freed. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

CVE-2026-33752

curlcffi is the a Python binding for curl. Prior to 0.15.0, curlcffi does not restrict requests to internal IP ranges, and follows redirects automatically via the underlying libcurl. Because of this, an attacker-controlled URL can redirect requests to internal services such as cloud metadata...

curl: Information disclosure via cross-protocol redirect with OAuth2 bearer token

A flaw was found in curl. When an OAuth2 Open Authorization bearer token is used for an HTTPS transfer, and that transfer performs a cross-protocol redirect to a different scheme like IMAP, LDAP, POP3, or SMTP, curl might incorrectly pass the bearer token to the new target host. This could lead t...

curl: curl: Unauthorized access due to improper HTTP proxy connection reuse

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...

curl: curl: Arbitrary code execution or Denial of Service via use-after-free in SMB request handling

A flaw was found in curl. When handling a second Server Message Block SMB request to the same host, curl incorrectly accesses memory that has already been freed. This memory corruption vulnerability, known as a use-after-free, could allow a remote attacker to potentially execute arbitrary code or...

curl: libcurl: Curl out of bounds read for cookie path

An out of bounds read flaw has been discovered in the curl project. Under specific conditions the path comparison logic makes curl read outside a heap buffer boundary. This bug either causes a crash or it potentially makes the comparison come to the wrong conclusion and lets the clear-text site...

curl: predictable WebSocket mask

A flaw was found in curl. The use of a predictable WebSocket mask pattern allows a malicious server to induce traffic that an intermediary proxy whether configured or transparent will misinterpret as a standard HTTP request. This confusion leads to a cache poisoning attack, where the proxy stores...

curl: curl: Security bypass due to global TLS option changes in multi-threaded LDAPS transfers

A flaw was found in curl. When performing multi-threaded LDAPS Lightweight Directory Access Protocol Secure transfers, changes to Transport Layer Security TLS options in one thread could inadvertently apply globally, affecting other concurrent transfers. This could lead to unintended security...
