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.

n8n workflows using the Oracle Database node are vulnerable to SQL injection via the Limit field. If your automation accepts external input (such as webhooks) that reaches these nodes, an attacker could exfiltrate data from your connected database. Users should upgrade to version 1.123.32, 2.17.4, or 2.18.1 to mitigate this risk.
