aiohttp: TLS Server Hostname Override Is Ignored When Reusing HTTPS Connections
Summary The serverhostname TLS SNI check can be bypassed when an existing connection is reused. Impact If an application makes multiple requests to the same domain, but with different per-request serverhostname parameters, then the later calls may succeed by reusing the existing connection when...

CVE-2026-7666
A flaw was found in Django. An on-path network attacker could exploit a vulnerability in django.core.mail.backends.smtp.EmailBackend where a partially-initialized connection is reused after a failed STARTTLS handshake when failsilently=True. This could allow the attacker to intercept and read ema...

curl: Connection reuse ignores haproxyprotocol and HAPROXY_CLIENT_IP settings, allowing PROXY context to persist across transfers
Summary: libcurl's connection pool match logic does not include the CURLOPTHAPROXYPROTOCOL setting or the CURLOPTHAPROXYCLIENTIP value in its connection match key. Two transfers issued through the same Curleasy or via a shared connection cache CURLLOCKDATACONNECT therefore share one TCP connectio...
