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 https://github.com/nodejs/undici/pull/4088.
If a webhook fails, avoid keep calling it repeatedly.
