node is vulnerable to Denial of Service (DoS)
42
Medium Risk
This Affects:
nodeTL;DR
Affected versions of Node.js are vulnerable to a crash due to node:zlib synchronous APIs asserting when a TypedArray byteLength is spoofed. Repeated exploitation can result in a denial of service (DoS).
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application calls the synchronous node:zlib APIs (for example, deflateSync/inflateSync) with an attacker-influenced TypedArray whose byteLength can be spoofed.
Background info
node is vulnerable to Denial of Service (DoS) in versions 25.0.0 - 26.5.0, 23.0.0 - 24.18.0 and 0.0.1 - 22.23.1.
How to fix this
Upgrade the node library to a patch version.
