# CVE-2026-106073: Node.js vulnerability

**Signal:** Normal patch cycle. No exploitation signal; fix it in your next routine update if you are affected. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog. That can change quickly after a public write-up; re-check if you are affected.
- Editorial verdict: Patch this week. Node.js October 2026 Security Releases: 10 CVEs Fixed — Four high-severity fixes, including a Brotli decoder memory-corruption bug the project says permits remote code execution, make this a routine-but-real upgrade: roll every supported line forward this week.

## What it is

Node.js 22.23.4, 24.22.1 and 26.12.1 fix a Brotli out-of-bounds write, TLS hostname bypasses and more. Not known exploited. Upgrade this week.

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
