Vulnerability from cvelistv5 – Published: 2026-08-11 12:17 – Updated: 2026-08-11 17:50

Title

n8n before 1.123.67 SQL Injection via PostgresTrigger Node

Summary

n8n before 1.123.67, 2.31.5, and 2.32.1 contains a SQL injection vulnerability in the PostgresTrigger node, which interpolates user-supplied identifier parameters (channel, function, and trigger names) into SQL statements without proper escaping. An authenticated user can inject arbitrary SQL executed against the connected PostgreSQL database with the configured credential's privileges, allowing full read and write access.

Severity

5.8 (Medium)
