Description

Undici is an HTTP/1.1 client, written from scratch for Node.js. In affected versions calling `fetch(url)` and not consuming the incoming body ((or consuming it very slowing) will lead to a memory leak. This issue has been addressed in version 6.6.1. Users are advised to upgrade. Users unable to upgrade should make sure to always consume the incoming body.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v < 6.6.16.0.0 ≤ v < 6.6.16.0.0
Affected range stops below 6.6.1, so it looks safe — our inference, not a vendor statement
