Node.js: Certificate Trust Fixes and TLS Throughput
Node.js tightened certificate trust with a public-key blocklist and root store update alongside several CVE-linked validation fixes. TLS reads were batched for performance, and shared-library builds were made stricter.

Hello, it's October 21st, 2026, and this is your Node.js daily briefing.
The clear pattern today is hardening trust, with a batch of certificate and input validation fixes, paired with a practical speed-up for encrypted traffic.
First, verification. Pull request 66871 adds a compiled-in blocklist of public key hashes checked during certificate verification. This matters because a compromised intermediate could still chain to a trusted root, and removing the whole root would over-block legitimate chains. The blocklist lets Node reject just…
Second, encrypted throughput. Pull request 66698 changes how buffered T L S records are delivered. Previously each record triggered its own allocation and call into JavaScript, which hurts with small records — N G I N X defaults to 4 kilobytes and some servers start near 1 kilobyte. Now Node keeps reading into the…
Third, build correctness and test overhead. Pull request 66844 stops passing vendored headers when building against shared libraries, forcing explicit dependencies, backed by expanded shared-library test coverage. Related work re-enables older Open S S L versions in that test matrix in pull request 66711 and…
What's next: if you build…
