CVE-2026-8458

A flaw was found in libcurl. A logical error in the connection pooling mechanism may cause libcurl to reuse an authenticated connection for an unintended service. This could allow an application to wrongfully reuse an existing connection to the same server that was authenticated for a different...

CVE-2026-56850

A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual TLS mTLS client identities to be reused across requests configured with different client certificates. This vulnerability affects Node.js 26.x, 24.x, and 22.x...

nodejs: Node.js: mTLS client identities can be reused due to HTTPS Agent connection flaw

A flaw was found in Node.js. The HTTPS Agent, responsible for managing secure connections, can incorrectly reuse client identities across different requests. This occurs due to a technical issue with PFX object-array key collisions during connection reuse. As a result, a client's identity,...

CVE-2026-10051

In Eclipse Jetty, a first HTTP/1.1 request with trailers causes the server to retain the trailers in subsequent requests performed over the same connection. Subsequent request that do not have trailers report the trailers of the first request. Subsequent request that do have trailers report the...

Security update for curl

This update for curl fixes the following issues CVE-2026-4873: connection reuse ignores TLS requirement bsc1262631. CVE-2026-8286: wrong STARTTLS connection reuse bsc1268402. CVE-2026-8458: wrong reuse for different services bsc1268407. CVE-2026-8924: traling dot domain super cookie bsc1268409...

SUSE CVE-2026-8286

A vulnerability exists where a new transfer that uses STARTTLS to upgrade the connection might reuse an existing live connection even though the TLS configuration mismatches so it should not...

SUSE 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...

SUSE 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-2026-8286

A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...

CVE-2026-8932

A flaw was found in curl. The libcurl library, used for transferring data with URLs, could improperly reuse existing network connections. This occurred even when changes to mutual Transport Layer Security mTLS settings, particularly those for client certificates, should have prevented such reuse...

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...
