NVD description
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.
What to do
- Upgrade n8n to
1.123.67or later (or the patched release of your branch: 2.31.5). - Do not expose the component's API or UI to the internet without authentication in front of it.
