urllib3: HTTPS proxy TLS configuration may be ignored or overridden

Impact urllib3 supports configuring TLS independently for an HTTPS proxy and the target server. proxysslcontext, proxyasserthostname, and proxyassertfingerprint configure the TLS connection to the proxy. sslcontext and the other target-specific TLS parameters configure the connection to the targe...

cipherTest.sh por Patrick Bogen cipherTest.sh es un "mejor" comprobador de cifrados SSL en el sentido de que utiliza gnutls, que tiene soporte para muchas más configuraciones que openssl. Prueba potencialmente 3,200 configuraciones diferentes pero realiza una pre-optimización para minimizar las...

CVE-2026-97687

A flaw was found in urllib3. This vulnerability allows a remote attacker on the network to intercept and alter data transmitted through an HTTPS proxy. The issue occurs when target-server Transport Layer Security TLS settings inadvertently overwrite the proxy's TLS configuration, which can disabl...

CVE-2026-92615: Improper Resource Locking

A flaw was found in flightctl. The configureRepoHTTPSClient function in the device-render worker builds a per-repository tls.Config which may include InsecureSkipVerify, a custom CA bundle, or tenant-supplied mTLS client certificates and installs it into go-git's process-global client.Protocols m...

CVE-2026-59272

A flaw was found in the Log4j2 AMQP Appender. When configured to ship logs to RabbitMQ over Transport Layer Security TLS, the appender disables hostname verification by default. This misconfiguration allows a remote attacker to perform a man-in-the-middle MITM attack, intercepting sensitive log...
