Amazon Linux 2023: CVE-2025-47279: Important priority package update for nodejs22 (Multiple Advisories)

Undici is an HTTP/1.1 client for Node.js. Prior to versions 5.29.0, 6.21.2, and 7.5.0, applications that use undici to implement a webhook-like system are vulnerable. If the attacker set up a server with an invalid certificate, and they can force the application to call the webhook repeatedly, then they can cause a memory leak. This has been patched in versions 5.29.0, 6.21.2, and 7.5.0. As a workaound, avoid calling a webhook repeatedly if the webhook fails.
A memory leak vulnerability has been discovered in the Undici HTTP/1.1 client library. This flaw can be triggered by repeatedly calling a webhook endpoint that presents an invalid TLS certificate. Continuous interaction with such an endpoint can cause the Undici library to allocate memory without properly releasing it, potentially leading to excessive memory consumption. Over time, this could result in resource exhaustion, impacting the availability and stability of applications relying on Undici for webhook communication.
