Upgrade n8n-nodes-base to version 2.24.0 or higher.
Overview
n8n-nodes-base is a Base nodes of n8n
Affected versions of this package are vulnerable to SQL Injection through the prepareItems logic used by the findOneAndReplace, findOneAndUpdate, and update operations in GenericFunctions.ts and MongoDb.node.ts. An authenticated workflow editor can supply a non-scalar updateKey value, such as an object or array, enabling the node to build a MongoDB query filter from attacker-controlled input. This lets the attacker match unintended documents and overwrite them with content of their choosing. For users running affected workflows, this can corrupt or replace data in MongoDB collections without the node rejecting the malicious filter value.
Workarounds
- Limit workflow creation and editing permissions to fully trusted users only; this prevents authenticated workflow editors from supplying a malicious
updateKeyvalue in the MongoDB node’s Find And Replace path. - Disable the MongoDB node by adding
n8n-nodes-base.mongoDbto theNODES_EXCLUDEenvironment variable; this blocks use of the vulnerable MongoDB node operations entirely.
