CVE-2026-54313
n8n: NoSQL Injection in MongoDB Node Find And Replace Operation
n8n is an open source workflow automation platform. Prior to 2.24.0, 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. This vulnerability is fixed in 2.24.0.

n8n: NoSQL Injection in MongoDB Node Find And Replace Operation
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.mongoDbto theNODES_EXCLUDEenvironment variable.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
