- Also known as: GHSA-65MV-V8RP-54WC, EUVD-2026-112376, GHSA-6VPF-74V5-9QCM
- Severity: CVSS 7.0 (High), CNA

- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.123.85, 2.44.1, 2.43.5
- Published: 2026-10-28 · Updated: 2026-10-29

## Summary

The vulnerability affects the n8n workflow automation platform, specifically its Quick Base integration node. An attacker who can supply untrusted input, such as webhook data used to build a query filter, can manipulate the request to read all records or delete every record in the connected Quick Base application using the workflow's credentials.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- n8n-io n8n: fixed in 1.123.85
- n8n-io n8n: from 2.44.0, fixed in 2.44.1
- n8n-io n8n: from 2.0.0, fixed in 2.43.5

## Description

n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 contains a filter injection vulnerability in the Quick Base node, which sends the Where filter to the Quick Base API as raw query text. Attackers supplying untrusted input such as webhook data used to build the filter can make Get Many return every record or Delete remove every record with the workflow credential's privileges.

## What to do

- Check your stack: if you ship or depend on n8n-io n8n, upgrade to a fixed version (1.123.85, 2.44.1, 2.43.5) per the references below.
