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.\n\n## Patches\nThe issue has been fixed in n8n version 2.24.0. Users should upgrade to this version or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Limit workflow creation and editing permissions to fully trusted users only.\n- Disable the MongoDB node by adding `n8n-nodes-base.mongoDb` to the `NODES_EXCLUDE` environment variable.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.\n\n## Affected packages\n\n- `n8n < 2.24.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `n8n 2.24.0`","depth":"sunlit","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
