GHSA-cxrh-j4jr-qwg3
undici Denial of Service attack via bad certificate data
Quick fix
GHSA-cxrh-j4jr-qwg3 — undici: upgrade to the fixed version with the command below.
npm install undici@5.29.0Details
### Impact
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.
### Patches
This has been patched in https://github.com/nodejs/undici/pull/4088.
### Workarounds
If a webhook fails, avoid keep calling it repeatedly.
