CVE-2026-126051
validatedZero produced an exploit or a check.description
Node.js 24.x and 26.x TLS servers can terminate when deferred handshake callbacks run after the underlying socket has been destroyed. A remote unauthenticated client can trigger the condition when the server uses SNICallback, OCSPRequest, newSession, resumeSession, or server.addContext().
mitigation
Upgrade Node.js to 24.22.3 or 26.13.1. Until upgraded, reduce exposure by disabling affected TLS handshake hooks where feasible.
fixed in 24.22.3, 26.13.1
outcome
Contextual check: a technique exists and was validated, but no deterministic check could cover this one.
