CVE-2026-11703 — Missing SNI/ALPN binding on stateful (session-ID) TLS session resumption

CVE-2026-11703

Missing SNI/ALPN binding on stateful (session-ID) TLS session resumption PUBLISHED

Description (CNA)

Missing SNI/ALPN binding on stateful (session-ID) resumption, which previously skipped the binding check performed for ticket-based resumption. A cached session could be resumed under a different SNI/ALPN than originally negotiated and, where client-authentication policy differs across virtual hosts, carry the cached peer-authentication state into a context it was not established for. Resumption now verifies the SNI/ALPN binding for all paths and declines (falling back to a full handshake) on mismatch.
