undici Denial of Service attack via bad certificate data
CVE-2025-47279 is fixed in 21 products on 1 platform, first by DEBIAN-CVE-2025-47279, released May 15, 2025. It is not reported as exploited. Patch Radar priority: Routine.
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.
