N8N · N8N · CVE-2026-42233
**Name of the Vulnerable Software and Affected Versions**
n8n versions prior to 1.123.32
n8n versions prior to 2.17.4
n8n versions prior to 2.18.1
**Description**
A flaw in the Oracle Database node's select operation allows 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, such as from a webhook, an attacker could inject arbitrary SQL to exfiltrate data from the connected Oracle database.
**Recommendations**
Update to version 1.123.32.
Update to version 2.17.4.
Update to version 2.18.1.
As a temporary workaround, avoid passing external input into the `Limit` field of the Oracle Database node.
