    SQL Injection

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to SQL Injection via the process of constructing SQL queries in the Snowflake and legacy MySQL v1 nodes when user-controlled input is directly interpolated into identifier fields such as table name, column name, or update key without proper escaping. An attacker can exfiltrate, modify, or delete data on the connected database by supplying crafted input through workflow expressions.

    How to fix SQL Injection?

    Upgrade n8n-nodes-base to version 1.121.23, 2.17.2, 2.18.1 or higher.

    Affected versions of this package are vulnerable to SQL Injection via the Limit field in the Oracle Database node when user-controlled input is passed through expressions without proper sanitization or parameterization. An attacker can execute arbitrary SQL commands and exfiltrate data from the connected Oracle database by injecting malicious input into the Limit field.

    Note: This is only exploitable if the Oracle Database node is configured to accept external input into the Limit field, such as from a webhook, and the workflow allows unauthenticated or untrusted access.

    How to fix SQL Injection?

    Upgrade n8n-nodes-base to version 1.121.23, 2.17.2, 2.18.1 or higher.

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to SQL Injection via the row:search and row:get operations in the SeaTable node when user-controlled input is passed through expressions into the searchTerm or rowId parameters. An attacker can access unauthorized data from the connected SeaTable base by injecting crafted input that manipulates the underlying SQL query.

    Notes: This is only exploitable if the workflow is configured to pass external user input into the affected parameters.

    How to fix SQL Injection?

    Upgrade n8n-nodes-base to version 1.121.23, 2.17.2, 2.18.1 or higher.

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the Form Trigger node. An attacker can execute arbitrary scripts in the context of users visiting a published form by injecting malicious payloads, potentially leading to form submission hijacking and phishing attacks.

    Note: The existing Content Security Policy prevents direct session cookie theft but does not stop script execution or manipulation of form actions.

    How to fix Cross-site Scripting (XSS)?

    Upgrade n8n-nodes-base to version 1.121.18, 2.11.2 or higher.

    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?

    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.

    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

    Permissive List of Allowed Inputs

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to Permissive List of Allowed Inputs in the Webhook Node's IP whitelist validation due to includes() method performing partial string matching instead of exact IP comparison. An attacker can gain unauthorized access to restricted endpoints by sending requests from an IP address that partially matches a whitelisted entry, thereby bypassing intended access controls.

    How to fix Permissive List of Allowed Inputs?

    Upgrade n8n-nodes-base to version 1.121.7, 2.2.0 or higher.

    >=1.36.0 <1.121.7>=2.0.0-rc.0 <2.2.0

    User Impersonation

    n8n-nodes-base is a Base nodes of n8n

    Affected versions of this package are vulnerable to User Impersonation via the Stripe Trigger node that does not verify incoming webhook requests against Stripe webhook signing secret. An attacker with valid webhook URL can execute unauthorized workflows by sending forged webhook events to the endpoint, bypassing signature verification.

    ##Workaround This vulnerability can be partially mitigated by deactivating affected workflows or restricting access to workflows containing Stripe Trigger nodes to trusted users only.

    How to fix User Impersonation?

    Upgrade n8n-nodes-base to version 1.121.5, 2.1.4, 2.2.2 or higher.

    >=0.147.0 <1.121.5>=2.0.0-rc.0 <2.1.4>=2.2.0 <2.2.2
    • H
    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.
