FKIE_CVE-2025-47279
Vulnerability from fkie_nvd - Published: 2025-05-15 18:15 - Updated: 2026-06-17 09:27
Severity
Summary
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.

En versiones anteriores a la 5.29.0, 6.21.2 y 7.5.0, las aplicaciones que usan undici para implementar un sistema similar a un webhook son vulnerables. Si el atacante configura un servidor con un certificado no v\u00e1lido y logra forzar la aplicaci\u00f3n a llamar al webhook repetidamente, puede causar una fuga de memoria. Esto se ha corregido en las versiones 5.29.0, 6.21.2 y 7.5.0. Como soluci\u00f3n alternativa, evite llamar a un webhook repetidamente si este falla."
