Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language.

Security Fix(es):

* undici: Undici Uses Insufficiently Random Values (CVE-2025-22150) * nodejs: Node.js Worker Thread Exposure via Diagnostics Channel (CVE-2025-23083) * nodejs: GOAWAY HTTP/2 frames cause memory leak outside heap (CVE-2025-23085)

Affected: Alpaquita:23: nodejs, Alpaquita:stream: nodejs, BellSoft Hardened Containers:23: nodejs, BellSoft Hardened Containers:stream: nodejs

Undici is an HTTP/1.1 client. Starting in version 4.5.0 and prior to versions 5.28.5, 6.21.1, and 7.2.3, undici uses `Math.random()` to choose the boundary for a multipart/form-data request. It is known that the output of `Math.random()` can be predicted if several of its generated values are known. If there is a mechanism in an app that sends multipart requests to an attacker-controlled website, they can use this to leak the necessary values. Therefore, an attacker can tamper with the requests going to the backend APIs if certain conditions are met. This is fixed in versions 5.28.5, 6.21.1, and 7.2.3. As a workaround, do not issue multipart requests to attacker controlled servers.

Affected: npm: undici

### Impact

[Undici `fetch()` uses Math.random()](https://github.com/nodejs/undici/blob/8b06b8250907d92fead664b3368f1d2aa27c1f35/lib/web/fetch/body.js#L113) to choose the boundary for a multipart/form-data request. It is known that the output of Math.random() can be predicted if several of its generated values are known.

If there is a mechanism in an app that sends multipart requests to an attacker-controlled website, they can use this to leak the necessary values. Therefore, An attacker can tamper with the requests going to the backend APIs if certain conditions are met.

### Patches

This is fixed in 5.28.5; 6.21.1; 7.2.3.

### Workarounds

Do not issue multipart requests to attacker controlled servers.
