    Prototype Pollution

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Prototype Pollution via the pagination parameter in the HTTP Request node. An attacker can execute arbitrary code on the instance by achieving global prototype pollution and chaining this with other techniques. This is only exploitable if the attacker is an authenticated user with permission to create or modify workflows.

    How to fix Prototype Pollution?

    Upgrade n8n-nodes-base to version 2.20.4, 2.21.1 or higher.

    Prototype Pollution

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Prototype Pollution in the Xml class, which implements an XML node. A user with permission to create or modify workflows can achieve remote code execution on the host system.

    Note: This is a bypass of the fix for the vulnerability described in CVE-2026-42232.

    How to fix Prototype Pollution?

    Upgrade n8n-nodes-base to version 2.20.4, 2.21.1 or higher.

    Arbitrary Argument Injection

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Arbitrary Argument Injection in a push operation. A user with permission to create or modify workflows can read arbitrary files on the server by injecting CLI flags during workflow creation or modification.

    How to fix Arbitrary Argument Injection?

    Upgrade n8n-nodes-base to version 1.121.29, 2.20.4, 2.21.1 or higher.

    Command Injection

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Command Injection via the Execute Command node. An attacker can execute arbitrary commands on the host system by leveraging access to an authenticated user account, potentially leading to data exfiltration, service disruption, or full system compromise.

    Note:

    This is only exploitable if the Execute Command node is enabled and not all user accounts are strictly controlled and trusted.

    This issue does not impact n8n.cloud.

    As per maintainers' memo: "No code changes have been made to alter the behavior of the Execute Command node. The recommended mitigation is to disable the node by default in environments where it is not explicitly required. Future n8n versions may change the default availability of this node."

    ##Workaround

    This vulnerability can be mitigated by disabling the Execute Command node before n8n start using the environment variable: export NODES_EXCLUDE: "[\"n8n-nodes-base.executeCommand\"]".

    How to fix Command Injection?

    There is no fixed version for n8n-nodes-base.
