CVE-2026-42233

n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, a flaw in the Oracle Database node's select operation allowed user-controlled input passed into the Limit field via expressions to be interpolated directly into the SQL query without sanitization or parameterization. In workflows where external input is passed into the Limit field (e.g., from a webhook), an attacker could inject arbitrary SQL and exfiltrate data from the connected Oracle database. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

Análisis

n8n users utilizing the Oracle Database node should update to version 1.123.32, 2.17.4, or 2.18.1. A SQL injection flaw in the Limit field allows attackers to exfiltrate data from connected databases if workflows are configured to pass unsanitized external input, such as webhook data, directly into the node's expressions.
