| n8n | = 2.18.0≥ 2.17.0, < 2.17.4< 1.123.32 | 2.17.41.123.32 |
| n8n | ≥ 2.17.0, < 2.17.4≥ 2.18.0, < 2.18.1< 1.123.32 | 2.17.42.18.11.123.32 |
An authenticated user with permission to create or modify workflows could achieve global prototype pollution via the XML Node leading to RCE when combined with other nodes exploiting the prototype pollution.
The issue has been fixed in n8n versions 1.123.32, 2.17.4, and 2.18.1. Users should upgrade to one of these versions or later to remediate the vulnerability.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
n8n-nodes-base.xml to the NODES_EXCLUDE environment variable.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
