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.
