Vulnerability from cvelistv5 – Published: 2026-08-04 00:49 – Updated: 2026-08-04 15:03
VLAI
Summary
A flaw in Node.js allows a spoofed `TypedArray` `byteLength` to trigger a reachable assertion in the synchronous `node:zlib` APIs, causing the entire process to crash. All 11 synchronous zlib functions are affected. Repeated exploitation of this condition can result in a denial of service. This vulnerability affects Node.js **22.x**, **24.x**, and **26.x**.
