Php-mod/curl Library <2.3.2 - Cross-Site Scripting

Php-mod/curl library before 2.3.2 contains a cross-site scripting vulnerability via the postfilepathupload.php key parameter and the POST data to postmultidimensional.php. An attacker can inject arbitrary script, which can allow theft of cookie-based authentication credentials and launch of other...

RealTek Jungle SDK - Arbitrary Command Injection

There is a command injection vulnerability on the "formWsc" page of the management interface. Successful exploitation of this vulnerability could lead to remote code execution and compromise of the affected system. id: CVE-2021-35395 info: name: RealTek Jungle SDK - Arbitrary Command Injection...

CURL-CVE-2026-8925 SASL double-free

The curl logic that works with SASL authentication could end up cleaning up the GSASL context twice without clearing the pointer in between, making it free the same pointer twice...

CURL-CVE-2026-11564 Native CA trust persist

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. An easy handle that first uses default native CA trust can continue trusting the native platform store after the application switches that same handle to custom CA...

CURL-CVE-2026-9545 exposing HTTP/3 early data

In this scenario, libcurl first uses a proper HTTP/3 server for the initial transfers, and when it makes a second transfer to the same site it has been replaced by the attacker's impostor machine - without a valid certificate. When libcurl returns to the hostname the second time with a cached SSL...

CURL-CVE-2026-8926 password leak with netrc and user in URL

When asking curl to use a .netrc file to find credentials and at the same time specifying a URL with a username without a password, like https://[email protected]/, curl could wrongly get and use the password for another user set in the .netrc file for that host if such a one exists and there is n...

CURL-CVE-2026-9080 UAF after pause in socket callback

Calling curleasypause within the event-based CURLMOPTSOCKETFUNCTION callback triggers a use-after-free vulnerability, where libcurl attempts to store a flag using a dangling struct pointer immediately after that pointer's memory has been freed...

CURL-CVE-2026-9547 SSH improper host validation

When a libcurl-based application performs transfers via SCP:// or SFTP:// and utilizes the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for th...

CURL-CVE-2026-8924 trailing dot domain super cookie

A flaw in curl’s cookie parsing logic allows a malicious HTTP server to set "super cookies" that bypass the Public Suffix List check. This enables an attacker-controlled origin to inject cookies that curl subsequently scopes and transmits to unrelated third-party domains...

UAF after pause in socket callback

Calling curleasypause within the event-based CURLMOPTSOCKETFUNCTION callback triggers a use-after-free vulnerability, where libcurl attempts to store a flag using a dangling struct pointer immediately after that pointer's memory has been freed...

CURL-CVE-2026-11586 WS Auto-PONG memory exhaustion

By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by flooding curl with rapid, sequential PING messages...

CURL-CVE-2026-8932 incomplete mTLS config matching in conn reuse

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS...

CURL-CVE-2026-11352 QUIC zero-length UDP datagrams busy-loop

An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can...

CVE-2026-50019

yt-dlp is a command-line audio/video downloader. From 2023.09.24 until 2026.06.09, if curl is used as an external downloader for yt-dlp, cookies may be leaked to an unintended host upon HTTP redirect or when the host for download fragments differs from their parent manifest's. At the file downloa...

CVE-2026-55568

Guzzle is an extensible PHP HTTP client. Prior to 7.12.1, in certain configurations, traffic expected to be protected by TLS on the hop to the proxy is transmitted in cleartext. Proxy authentication credentials the Proxy-Authorization header, proxy userinfo in the proxy URL, or CURLOPTPROXYUSERPW...

CVE-2026-50019

Summary of CVE-2026-50019 (yt-dlp) : When curl is used as an external downloader, yt-dlp may leak cookies to unintended hosts during HTTP redirects or when the host for download fragments differs from the manifest. At the file-download stage, cookies are passed via --cookie; unless cookies are lo...

CVE-2026-55568

Summary (CVE-2026-55568) : Guzzle’s built‑in cURL handlers (CurlHandler/CurlMultiHandler) can downgrade an https:// proxy to plaintext when using libcurl older than 7.50.2, exposing proxy credentials and the CONNECT host/port. The issue occurs if an https proxy is configured and the app runs with...
