n8n@1.90.2

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Prototype Pollution via the GSuiteAdmin node parameter. An attacker with permissions to create or modify workflows can execute arbitrary code by supplying crafted parameters that pollute Object.prototype during workflow creation or modification.

Upgrade n8n to version 1.123.27, 2.13.3, 2.14.1 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to SQL Injection in the orderByColumn expression of the Data Table Get node. An attacker with permissions to create or modify workflows can execute arbitrary SQL commands by supplying crafted input, potentially leading to unauthorized data access, modification, or deletion.

Note: This is only exploitable if the Data Table node is enabled.

Upgrade n8n to version 1.123.27, 2.13.3, 2.14.1 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Arbitrary Code Injection via the Merge node's Combine by SQL mode. An authenticated user with permissions to create or modify workflows can execute arbitrary code and access sensitive files on the host by crafting malicious SQL statements when creating or modifying workflows.

Upgrade n8n to version 1.123.27, 2.13.3, 2.14.1 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Incorrect Authorization when saving credentials. An authenticated user can access plaintext values of secrets stored in external vaults by referencing a secret's external name in a credential, bypassing intended permission checks.

Note: This is only exploitable if an external secrets vault is configured and the attacker knows or can guess the name of a target secret.

Upgrade n8n to version 1.123.23, 2.6.4 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key in the Source Control feature when configured to use SSH, as the SSH command disables host key verification. An attacker can intercept repository data or inject malicious content by performing a man-in-the-middle attack between the affected instance and the remote Git server.

Upgrade n8n to version 2.5.0 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to User Impersonation in the account linking when LDAP authentication is enabled. An attacker can gain unauthorized access to another user's account, including administrative accounts, by setting their LDAP email attribute to match the target user's email. This linkage persists even if the LDAP email is later changed, resulting in permanent unauthorized access.

Upgrade n8n to version 1.121.0 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Incorrect Authorization in the OAuth callback when the N8N_SKIP_AUTH_ON_OAUTH_CALLBACK environment variable is set to true. An attacker can gain unauthorized access to OAuth tokens by tricking a victim into completing an OAuth flow against a credential object controlled by the attacker, allowing the attacker to execute workflows as the victim.

Upgrade n8n to version 2.6.4, 2.7.3 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the Credential Management Flow when a crafted OAuth2 credential contains a JavaScript URL in the Authorization URL field. An attacker can execute arbitrary scripts in the victim's browser session by convincing an authenticated user with permission to create and share credentials to interact with the OAuth authorization button.

Upgrade n8n to version 2.6.4, 2.8.0 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Improper Authentication via the Self-Service Settings API. An attacker can circumvent centralized identity management and multi-factor authentication by disabling SSO enforcement for their own account and creating local credentials after authenticating through SSO.

Upgrade n8n to version 2.8.0 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Command Injection in the community package installation functionality. An attacker can execute arbitrary system commands by supplying crafted input as an authenticated user with administrative permissions.

Note:

This is only exploitable if the attacker has administrative access to the instance and is permitted to install third-party community packages.

Upgrade n8n to version 1.119.2, 1.120.3 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Improper Validation of Specified Type of Input that is passed to the handleFormData() function. An attacker can gain unauthorized access to files on the underlying server by requests with unexpected content-type values to exposed webhook listeners. This allows the attacker to make arbitrary file contents available via means such as the chat interface. Sensitive cookie values retrieved can then be used to bypass authentication and further compromise of the application and underlying system.

Note:

For users using the main n8n package it is recommended to upgrade to n8n@1.121.0.

Upgrade n8n to version 1.121.0 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Improper Validation of Specified Type of Input that is passed to the handleFormData() function. An attacker can gain unauthorized access to files on the underlying server by requests with unexpected content-type values to exposed endpoints. This allows the attacker to make arbitrary file contents available via the chat interface. Sensitive cookie values retrieved can then be used to bypass authentication and further compromise of the application and underlying system.

Note:

For users using the main n8n package it is recommended to upgrade to n8n@1.121.0.

##Workaround This vulnerability can be mitigated by restricting or disabling publicly accessible webhook and form endpoints.

Upgrade n8n to version 1.121.0 or higher.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the Respond to Webhook node when it responds with HTML content containing executable scripts. An attacker can execute arbitrary JavaScript in the context of the editor interface by crafting a malicious workflow to bypass the sandbox, leading to unauthorized reading or modification of workflow data, insertion of malicious logic, or exfiltration of sensitive information from within an authenticated session.

n8n-auth session cookies are not exposed by this vulnerability.

Upgrade n8n to version 1.114.0 or higher.

n8n is a n8n Workflow Automation Tool

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\"]".

There is no fixed version for n8n.

n8n is a n8n Workflow Automation Tool

Affected versions of this package are vulnerable to Missing Authorization over the /rest/executions/:id/stop endpoint, which can execute stop a workflow operation on workflows not owned by the user. Long-running and time-sensitive workflows are particularly vulnerable.

Upgrade n8n to version 1.99.1 or higher.
