How severe is GHSA-jqwr-vx3p-r266?

No CVSS score has been assigned to GHSA-jqwr-vx3p-r266 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-jqwr-vx3p-r266?

GHSA-jqwr-vx3p-r266 affects the following packages: n8n (npm), n8n (npm), n8n (npm). Ecosystems affected: npm.

How do I fix GHSA-jqwr-vx3p-r266?

Update n8n to 1.123.67 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jqwr-vx3p-r266 is resolved across your whole dependency graph.

How do I detect GHSA-jqwr-vx3p-r266 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-jqwr-vx3p-r266 if there is no patch (or I can't update yet)?

Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.

Is GHSA-jqwr-vx3p-r266 actively exploited in the wild?

No public exploit code has been indexed for GHSA-jqwr-vx3p-r266 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-jqwr-vx3p-r266?

GHSA-jqwr-vx3p-r266 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 40th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-jqwr-vx3p-r266?

GHSA-jqwr-vx3p-r266 is classified as SQL Injection (CWE-89). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-jqwr-vx3p-r266 published, and has it been updated?

GHSA-jqwr-vx3p-r266 was published on July 22, 2026 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

The Postgres Trigger node interpolated user-supplied identifier parameters (channel, function, and trigger names) into SQL statements without proper escaping, so an authenticated user could inject arbitrary SQL executed against the connected PostgreSQL database with the configured credential's privileges.

Successful exploitation allows full read and write access to the connected PostgreSQL database.

Patches

The issue has been fixed in n8n versions 1.123.67, 2.31.5 and 2.32.1. Users should upgrade to these versions or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

Restrict n8n instance access to fully trusted users only.
Disable the PostgresTrigger node by adding n8n-nodes-base.postgresTrigger to the NODES_EXCLUDE environment variable.
Ensure PostgreSQL credentials used with n8n are configured with the minimum required privileges and do not use SUPERUSER roles.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
