## Overview

## Impact
An authenticated user with workflow edit access could supply a malicious filter value in the MongoDB node's Find And Replace operation. The value was not validated before being passed to MongoDB as a query filter, allowing unintended documents to be matched and overwritten with attacker-controlled content.

## Patches
The issue has been fixed in n8n version 2.24.0. Users should upgrade to this version 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 MongoDB node by adding `n8n-nodes-base.mongoDb` to the `NODES_EXCLUDE` environment variable.

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

## Affected packages

- `n8n < 2.24.0`

## Remediation

Upgrade to a patched release:

- `n8n 2.24.0`
