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...

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...
libcurl 7.64.1 < 8.22.0 Negotiate Ambient User Connection Reuse
The version of libcurl installed on the remote host is 7.64.1 prior to 8.22.0. It is, therefore, affected by an information disclosure vulnerability: - A flaw in libcurl makes it wrongly reuse an HTTP connection setup for a given hostname using Negotiate authentication, when the initial request i...

OpenSSL pinning bypass
When CURLOPTPINNEDPUBLICKEY is configured alongside options that disable standard peer verification CURLOPTSSLVERIFYPEER = 0 and CURLOPTSSLVERIFYHOST = 0, libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check und...

Negotiate ambient user conn reuse
A flaw in libcurl makes it wrongly reuse an HTTP connection setup for a given hostname using Negotiate authentication, when the initial request is done using empty credentials. This can make user B's request get sent over user A's previously authenticated connection...
CURL-CVE-2026-80230 OpenSSL pinning bypass

Bypassing the pinning check und...
CURL-CVE-2026-82208 wolfSSL CA-cache hit overrides callback
With the wolfSSL backend, when CA caching is enabled and an CURLOPTSSLCTXFUNCTION callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectl...
