CVE-2025-47279
undici Denial of Service attack via bad certificate data
Impact
### 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. ### References Reported as: https://github.com/nodejs/undici/issues/3895
