FKIE_CVE-2025-68949

Vulnerability from fkie_nvd - Published: 2026-01-13 19:16 - Updated: 2026-01-16 18:47
Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
n8n is an open source workflow automation platform. From 1.36.0 to before 2.2.0, the Webhook node’s IP whitelist validation performed partial string matching instead of exact IP comparison. As a result, an incoming request could be accepted if the source IP address merely contained the configured whitelist entry as a substring. This issue affected instances where workflow editors relied on IP-based access controls to restrict webhook access. Both IPv4 and IPv6 addresses were impacted. An attacker with a non-whitelisted IP could bypass restrictions if their IP shared a partial prefix with a trusted address, undermining the intended security boundary. This vulnerability is fixed in 2.2.0.

Este problema afectaba a las instancias donde los editores de flujos de trabajo depend\u00edan de controles de acceso basados en IP para restringir el acceso a los webhooks. Tanto las direcciones IPv4 como IPv6 se vieron afectadas. Un atacante con una IP no incluida en la lista blanca pod\u00eda eludir las restricciones si su IP compart\u00eda un prefijo parcial con una direcci\u00f3n de confianza, socavando el l\u00edmite de seguridad previsto.
