Impact Undici fetch() 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 req

Level up your testing skills by learning directly from me! Read more Honestly, I'd never thought I'd be writing about this, but the matter of patching globals turned out to be one of those topics that a lot of engineers seem to misunderstand. Most of us don't do monkey-patching, and even fewer stay around those implementations long enough to witness their impact. All the more reason to talk about

Loading experience is crucial to the userâs first impression and overall usability, so Google defined Largest Contentful Paint (LCP) metric to measure how quickly the main content loads and is displayed to the user. This new attribute will enable us to fine-tune relative resource priority, improve LCP performance, deprioritize JavaScript fetch calls, and much more. Letâs check out fetchpriority an
Node.js v17.5 introduces support for fetch() â a popular cross-platform HTTP client API that works in browsers and Web/Service Workers â as an experimental core feature. fetch() support has been a long-requested addition by many, who want to write cross-platform HTTP request code and are familiar with the fetch() API shape and call patterns. So much so that the node-fetch module exists solely to b
