CVE-2026-54310

MEDIUM

n8n: SQL Injection in Postgres v1/TimesclaeDB Nodes

Published June 16, 2026Updated July 20, 2026Source: osv

Summary

## Impact 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. ## Patches 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. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Limit workflow creation and editing permissions to fully trusted users only. - Disable the Postgres and TimescaleDB node by adding `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.
