CVE-2026-54306

בינונית 6.4

תיאור (מקור, אנגלית)

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.
