Access Control Bypass

Overview Affected versions of this package are vulnerable to Access Control Bypass in the connection reuse process. An attacker can gain unauthorized access to resources or services by exploiting the reuse of an authenticated connection intended for a different service. Remediation Upgrade libcur...

Authentication Bypass by Primary Weakness

Overview Affected versions of this package are vulnerable to Authentication Bypass by Primary Weakness due to incomplete matching of mTLS configuration options during connection reuse in the connection process. An attacker can cause connections to be reused with incorrect client certificate...

CVE-2026-8932

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...

CVE-2026-8458

libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated ones, even when they are set to use different "services". libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead. When...

ALPINE-CVE-2026-11564

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...

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...

CVE-2026-8932

The libcurl library contains a vulnerability where it may incorrectly reuse an existing connection from its connection pool even when mTLS (mutual TLS) configuration options have been changed in a way that should prohibit reuse. The root cause is that certain TLS settings related to client certif...
