GHSA-JPQ7-226W-6CXX
Vulnerability from github – Published: 2026-06-16 18:59 – Updated: 2026-06-16 18:59Impact
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.
