CVE-2026-13608

A flaw in the libcurl SASL negotiation for LDAP authentication allows an incomplete handshake sequence to be misinterpreted as a successful cryptographic verification. An attacker executing a Man-in-the-Middle MITM attack can inject a premature or shortcut response that bypasses complete peer...

CVE-2026-13608 OpenLDAP SASL authentication bypass

A flaw in the libcurl SASL negotiation for LDAP authentication allows an incomplete handshake sequence to be misinterpreted as a successful cryptographic verification. An attacker executing a Man-in-the-Middle MITM attack can inject a premature or shortcut response that bypasses complete peer...

CVE-2026-13608

CVE-2026-13608 is an authentication bypass in libcurl's SASL negotiation for LDAP. An incomplete handshake sequence can be misinterpreted as a successful cryptographic verification, allowing a Man-in-the-Middle attacker to inject a premature or shortcut response that bypasses complete peer valida...

OESA-2026-3678 curl security update

cURL is a computer software project providing a library libcurl and command-line tool curl for transferring data using various protocols. Security Fixes: 'Hello friends,', 'CVE-2026-8286: wrong STARTTLS connection reuse LOW', 'CVE-2026-8458: wrong reuse for different services LOW', 'CVE-2026-8924...

K000163213: libcurl vulnerability CVE-2026-8932

Security Advisory Description 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 t...

curl: libcurl: Use-after-free in HTTP/2 Server Push with shared connections

A flaw was found in libcurl. When libcurl handles HTTP/2 Server Push streams and the parent handle shares connections, a use-after-free vulnerability can occur during the cleanup process. This could lead to application crashes, resulting in a denial of service...

curl: libcurl: Information disclosure via incorrect connection reuse with Negotiate authentication

A flaw was found in libcurl. This vulnerability allows an attacker to reuse an HTTP connection set up for a given hostname using Negotiate authentication. When an initial request is made with empty credentials, a subsequent user's request can be sent over a previously authenticated connection...

curl: curl: Authentication bypass in OpenLDAP SASL negotiation via Man-in-the-Middle (MITM) attack

A flaw was found in libcurl's SASL Simple Authentication and Security Layer negotiation for LDAP Lightweight Directory Access Protocol authentication when using the OpenLDAP backend. An incomplete handshake sequence can be misinterpreted as a successful cryptographic verification. A remote...

curl: libcurl: Information disclosure via improper Public Suffix List boundary check

A flaw was found in libcurl when libpsl support is enabled. A remote attacker could exploit this vulnerability by setting a Set-Cookie header with a Domain attribute that explicitly matches a public suffix. This improper handling causes libcurl to save the cookie with a wildcard domain scope,...

curl: curl: Public key pinning bypass allows unauthenticated connections

A flaw was found in libcurl, a client-side URL transfer library. When public key pinning is configured, but standard peer verification is explicitly disabled, libcurl incorrectly allows connections to proceed without enforcing the public key pinning. This bypass enables unauthenticated connection...

curl: libcurl: Information disclosure via incorrect connection reuse with Negotiate authentication

A flaw was found in libcurl. This vulnerability allows an attacker to reuse an HTTP connection set up for a given hostname using Negotiate authentication. When an initial request is made with empty credentials, a subsequent user's request can be sent over a previously authenticated connection...

curl: libcurl: Use-after-free in HTTP/2 Server Push with shared connections

A flaw was found in libcurl. When libcurl handles HTTP/2 Server Push streams and the parent handle shares connections, a use-after-free vulnerability can occur during the cleanup process. This could lead to application crashes, resulting in a denial of service...

curl: curl: Incorrect HTTPS connection reuse with Native CA Store

A flaw was found in libcurl. This vulnerability allows libcurl to incorrectly reuse an existing HTTPS connection for a given hostname, even when a different Native CA Store setting CURLSSLOPTNATIVECA is specified for the new connection. This could potentially lead to a client trusting a malicious...

libcurl 7.44.0 < 8.22.0 HTTP/2 Server Push Use-After-Free

The version of libcurl installed on the remote host is 7.44.0 prior to 8.22.0. It is, therefore, affected by a use-after-free vulnerability: - A flaw in libcurl's handling of HTTP/2 Server Push streams, when the parent handle is set to share connections with other handles, can lead to...
