    Eval Injection

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Eval Injection. An attacker can execute arbitrary code on the host system by submitting specially crafted form data that is interpreted as an expression.

    Note:

    This is only exploitable if a workflow contains a form node with a field that interpolates unauthenticated user input and the field value begins with an '=' character, causing double evaluation of the content.

    How to fix Eval Injection?

    Upgrade n8n-nodes-base to version 1.121.15, 2.9.1, 2.10.1 or higher.

    Exposure of Sensitive System Information to an Unauthorized Control Sphere

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Exposure of Sensitive System Information to an Unauthorized Control Sphere due to insufficient restrictions in the Python Code node sandbox. An attacker can access sensitive files or execute arbitrary code by escaping the sandbox environment.

    How to fix Exposure of Sensitive System Information to an Unauthorized Control Sphere?

    Upgrade n8n-nodes-base to version 2.7.0 or higher.

    Arbitrary Code Injection

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Arbitrary Code Injection via the Merge node's SQL query mode. An attacker can execute arbitrary code and write arbitrary files on the server by crafting malicious workflows after authenticating with permissions to create or modify workflows.

    How to fix Arbitrary Code Injection?

    Upgrade n8n-nodes-base to version 1.121.15, 2.9.1, 2.10.1 or higher.

    <1.121.15>=2.0.0 <2.9.1>=2.10.0 <2.10.1

    Protection Mechanism Failure

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Protection Mechanism Failure via the Python Code node. An attacker can execute arbitrary code outside the intended security boundary by leveraging authenticated access and enabling Task Runners with Python support. This is only exploitable if Task Runners are enabled (N8N_RUNNERS_ENABLED=true), Python support is enabled (N8N_PYTHON_ENABLED=true), and the Code Node is enabled (default: true).

    How to fix Protection Mechanism Failure?

    Upgrade n8n-nodes-base to version 2.3.0 or higher.

    <2.3.0
    • C
    Command Injection

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Command Injection via the Git node. An attacker can execute arbitrary system commands or read arbitrary files on the host by creating or modifying workflows as an authenticated user with the necessary permissions.

    How to fix Command Injection?

    Upgrade n8n-nodes-base to version 1.121.11, 2.5.2 or higher.

    <1.121.11>=2.0.0-rc.0 <2.5.2

    Arbitrary File Upload

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Arbitrary File Upload via the Merge node's SQL Query mode. An attacker can write arbitrary files to the server's filesystem and potentially execute remote code by crafting malicious workflows.

    Note:

    This is only exploitable if the attacker has authenticated access with permissions to create or modify workflows.

    How to fix Arbitrary File Upload?

    Upgrade n8n-nodes-base to version 1.121.12, 2.4.0 or higher.

    <1.121.12>=2.0.0 <2.4.0

    Directory Traversal

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Directory Traversal via the SSH node when workflows process uploaded files and transfer them to remote servers without validating their metadata. An attacker can write files to unintended locations on remote systems and potentially achieve remote code execution by uploading specially crafted files to unauthenticated endpoints.

    Note:

    This is only exploitable if the attacker has knowledge of such workflows and the endpoints for file uploads are unauthenticated.

    How to fix Directory Traversal?

    Upgrade n8n-nodes-base to version 1.121.7, 2.3.2 or higher.

    <1.121.7>=2.0.0 <2.3.2

    Unsafe Dependency Resolution

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Unsafe Dependency Resolution via the Git Node component. An attacker can execute arbitrary code within the environment by cloning a repository containing a malicious pre-commit hook and triggering the commit operation. This can compromise the system and any connected credentials or workflows.

    Note:

    This is only exploitable if workflows utilize the Git Node to clone untrusted repositories.

    How to fix Unsafe Dependency Resolution?

    Upgrade n8n-nodes-base to version 1.111.0 or higher.

    <1.111.0

    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.
