Please check if the PR fulfills these requirements

  • Followed the Contributing and Code of Conduct guidelines.
  • Tests for the changes have been added (for bug fixes/features) with 100% code coverage.

What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

Security fix. Bump the exact Node.js runtime pin for the November 11, 2026 Node.js security releases. No application code changed. Published engines ranges are unchanged.

Pins

Pin Old New
.nvmrc 24.18.0 24.22.3

Left unchanged:

  • GitHub Actions node-version values 22, 24, and 26 (floating majors, no patch, no digest).
  • Published engines ranges (>=22 on packages, ^22.19.0 \|\| >=24.0.0 at the repo root).
  • Dev Container image mcr.microsoft.com/devcontainers/javascript-node:5.2.1-24-trixie (major 24 plus a digest). The pinned digest still matches the current MCR manifest index for that tag. No 24.22.3 variant of that image is published.

v24.22.3 is on the Node.js dist index (2026-11-10). Official Docker Hub node:24.22.3 tags are not published yet. This repository has no Node image pin, so no image tag or digest was changed.

CVEs

Highest severity is HIGH. No active exploitation is reported. Patched lines are Node.js v22.23.5, v24.22.3, and v26.13.1. This repository only pins 24.x, so the pin moves to 24.22.3.

  • CVE-2026-123863 — HTTP/2 remote abort (CHECK_EQ in ~Http2Session()), affects 24.x/26.x
  • CVE-2026-123864 — HTTPS zero-length TLS write re-enters llhttp_execute()
  • CVE-2026-123865 — HTTP/2 session leak on protocol error during shutdown
  • CVE-2026-123866 — HTTP/2 stream teardown can send freed response memory
  • CVE-2026-123874 — HTTP/2 use-after-free in respondWithFile() during a pending write
  • CVE-2026-123875 — HTTP/2 NULL dereference when a respondWithFile() download is cancelled
  • CVE-2026-123828 — HTTP/2 heap-buffer-overflow in session.altsvc()
  • CVE-2026-123868 — HTTP/2 inbound data not charged to maxSessionMemory
  • CVE-2026-126051 — remotely triggerable uncaught exception in TLS servers via deferred handshake callbacks
  • CVE-2026-123872 — TLS 1.2 renegotiation can change servername and bypass client-certificate authentication
  • CVE-2026-123867 — CA-only SNI client-CA overrides fail open to the default CA
  • CVE-2026-123871 — proxy credentials disclosed in ERR_PROXY_INVALID_CONFIG
  • CVE-2026-123877 — certificate validation bypass in https.Agent via cross-policy TLS session reuse

Also includes llhttp, undici, and sqlite dependency updates in the Node.js release.

After merge

Rebuild and redeploy is required after merge (for runtime images). This library has no runtime image; the change is the local/dev .nvmrc pin used by nvm use.

No minimumReleaseAgeExclude entry was added.
