CVE-2026-125402 Ettercap through 0.8.4.1 Heap Out-of-Bounds Read via TLS SNI Parsing

Ettercap through 0.8.4.1 contains a heap out-of-bounds read vulnerability in sslwgetclienthellosni in src/ecsslwrap.c that trusts the unchecked 16-bit SNI length field. Network-adjacent attackers can send crafted TLS ClientHello messages during SSL interception to leak up to 64 KB of heap memory...

io.netty/netty-handler: Netty: SNI Routing Bypass via Fragmented TLS ClientHello Causing Fallback to Default SslContext

A flaw was found in Netty, an asynchronous, event-driven network application framework. An unauthenticated remote attacker can exploit fragmented Transport Layer Security TLS ClientHello messages to bypass the Server Name Indication SNI routing mechanism. This forces a fallback to a less secure...

CVE-2026-114635

A flaw was found in Traefik. The application improperly skips Server Name Indication SNI checks when processing certain Transport Layer Security TLS connection states. An unauthenticated remote attacker can exploit this issue by sending crafted HTTP/2 requests over TLS to bypass client certificat...

CVE-2026-116542

A flaw was found in netty-tcnative. A remote, unauthenticated attacker can exploit this issue by sending a specially crafted Server Name Indication SNI hostname with overlong character encodings during a Transport Layer Security TLS handshake. This causes the application to decode the hostname...

tomcat: Apache Tomcat: Improper Input Validation allows HTTP/2 no-authority bypass of strict SNI validation

A flaw was found in Apache Tomcat. This improper input validation vulnerability, stemming from an incomplete fix for CVE-2026-32990, allows for an HTTP/2 no-authority bypass of strict Server Name Indication SNI validation. This could potentially lead to unauthorized access or misrouting of reques...
