| Package | Affected versions | Patched versions |
|---|---|---|
| n8n | ≥ 2.26.0, < 2.26.2< 2.25.7 | 2.26.22.25.7 |
| n8n | ≥ 2.26.0, < 2.26.2< 2.25.7 | 2.26.22.25.7 |
An authenticated user with permission to create or modify workflows could supply a crafted parameters to the TimescaleDB and/or legacy Postgres v1 node's allowing arbitrary SQL to be injected and executed against the connected database within the privileges of the configured database account.
The issue has been fixed in n8n versions 2.25.7, and 2.26.2. Users should upgrade to one of these versions or later to remediate the vulnerability.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
n8n-nodes-base.postgres, n8n-nodes-base.timescaleDb to the NODES_EXCLUDE environment variable.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
