What Node.js versions need these security updates?

20.x, 22.x, 24.x, 25.x — all major lines. Grab the latest in each.

Are these Node.js vulnerabilities exploitable in production?

Yes. DoS crashes, side-channels, permission bypasses. Remote HTTP/TLS triggers common.

Not yet. Experimental, freshly bugged. Wait for stability unless you sandbox test.

Use NVM, n, or official binaries. npm install -g node@latest for active lines.
