Node.js: Crypto Hardening and a Cluster of Security Fixes
A major crypto overhaul dropping OpenSSL 1.x support headlines a day dominated by security-shaped bug fixes, spanning a FIPS bypass in Argon2, a heap overflow in mkdtemp, and two separate hardening fixes in single executable application parsing.

You're listening to Node.js, your daily briefing for July 27th, 2026.
Today's biggest signal is crypto. Panva opened PR 64777, a draft that requires OpenSSL 3 going forward and removes the runtime FIPS API entirely. The reasoning is blunt: FIPS features built on OpenSSL 1.x either never worked correctly or no longer mean what they claim. This is a draft pending build changes to…
Security-shaped fixes showed up elsewhere too. Frandle331 fixed a one-byte heap buffer overflow in the temporary directory creation function, mkdtemp, caught by AddressSanitizer, in PR 64770. Archkon landed two fixes for single executable applications: one rejecting trailing content in configuration JSON in PR…
A second theme is correctness in networking primitives. Archkon's dns fix, merged as commit 54a5095, stops reverse lookups from consulting the hosts file, aligning dns.reverse with the documented DNS-only behavior of resolve methods. On the QUIC side, manNomi's PR 64577 fixes reset codes serializing incorrectly, and…
What's next: watch PR 64777 as it moves toward alpha builds for version 27, since it signals FIPS API removal is coming. Also expect follow-up review on the REPL promise garbage…
That's…
