CVE-2026-54306 · n8n: Prototype Pollution enables confused-deputy execution via public webhooks
Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.
n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, a prototype pollution vulnerability allowed a crafted public webhook payload to inject attacker-controlled fields into workflow data during internal object copying. These fields could be surfaced and consumed as normal values by downstream built-in nodes. Where a workflow combines a public webhook with action nodes that consume the resulting fields, an attacker could cause the workflow to act as a confused deputy — targeting unintended records or issuing outbound requests using the workflow owner's configured credentials. This vulnerability is fixed in 2.25.7 and 2.26.2.
