Lifecycle Timeline

AnalysisAI
TLS session resumption in Node.js fails to bind reusable sessions to the originally authenticated host, enabling an information disclosure pathway. Affected versions are Node.js 26.x prior to 26.3.1 (Current channel), as disclosed in the June 2026 security release. An attacker with low network-level privilege can cause a cached TLS session-established and authenticated against one hostname-to be reused for a distinct, attacker-influenced host, potentially bypassing host-based authentication. No public exploit code or CISA KEV listing is present at time of analysis.
Technical ContextAI
Node.js implements TLS via its native tls module, wrapping OpenSSL session resumption mechanisms (session IDs and session tickets). TLS session resumption allows a client to skip the full handshake by reusing cryptographic state from a prior connection, identified by a session ticket or ID. The root cause here is that Node.js did not enforce that a cached session object is scoped exclusively to the hostname against which it was originally authenticated. When an application establishes TLS connections to multiple hosts-or when a session cache is shared across connection targets-a session validated for host A could be incorrectly resumed against host B, undermining the trust anchor of the TLS handshake. The fix commit (tls: bind reusable sessions to authenticated host) enforces hostname binding on session reuse. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) and 'Information Disclosure' tag confirm the scope is limited to confidentiality. No CWE was formally assigned; this maps most naturally to CWE-295 (Improper Certificate Validation) or CWE-297 (Improper Validation of Certificate with Host Mismatch).
RemediationAI
Upgrade Node.js to version 26.3.1 (Current) or later, which is confirmed to contain the fix via commit attributed to Matteo Collina. The vendor advisory and release notes are available at https://nodejs.org/en/blog/vulnerability/june-2026-security-releases and https://github.com/nodejs/node/releases/tag/v26.3.1. If an immediate upgrade is not feasible, a targeted workaround is to disable TLS session resumption in application code by setting secureOptions to suppress session caching (tls.createSecureContext with sessionTimeout: 0 or by not reusing session event data). The trade-off is increased handshake latency and CPU overhead on high-connection-volume services. Applications that exclusively connect to a single TLS endpoint (no multi-host session sharing) have minimal practical exposure but should still patch to eliminate the class of risk. Whether LTS lines require separate patches should be confirmed via the Node.js security blog before assuming non-26.x deployments are safe.
