CVE-2026-11703

The CVE-2026-11703 entry describes a vulnerability in stateful (session-ID) TLS resumption where missing SNI/ALPN binding allowed a cached session to be resumed under a different SNI/ALPN than originally negotiated. The root cause is the absence of binding checks for stateful resumption paths, wh...

CVE-2026-55960

Un-negotiated Raw Public Key RFC 7250 accepted in place of an X.509 certificate, bypassing chain validation. A raw public key has no chain, so ParseCertRelative accepts it without performing any trust verification; it must therefore only be accepted when RPK was actually negotiated for that peer...
