CVE-2026-94200Network attack vectorHinoki check available

TLS shutdown via session-ticket extension confusion

Published Oct 14, 2026 · Updated Oct 14, 2026

Ticket parsing in Erlang/OTP ssl allows remote attackers to crash the client ticket store via crafted TLS 1.3 server messages. tls_handshake_1_3 decodes NewSessionTicket extensions as EncryptedExtensions, accepting an empty early_data value that get_max_early_data cannot handle. Automatic session-ticket management and later resumption are required; repeated store crashes exceed supervisor restart limits and shut down ssl across the node.
