Summary

Undici is an HTTP/1.1 client for Node.js. In versions prior to 5.29.0, 6.x prior to 6.21.2, and 7.x prior to 7.5.0, applications that use undici to implement a webhook-like system are vulnerable. If the attacker sets 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. As a workaround, avoid calling a webhook repeatedly if the webhook fails.

CWE-401 - Missing release of memory after effective lifetime (memory leak)

'Missing release of memory after effective lifetime (memory leak)' is a weakness that occurs when software doesn't effectively release allocated memory after it is used. If not addressed, this enables attackers to launch denial of service attacks (by crashing or hanging the program) or take advantage of other unexpected behavior resulting from low memory conditions.
