CVE-2026-54313
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.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
Description
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.
