CWE
- CWE-918 - Server-Side Request Forgery (SSRF)
Summary
n8n before 1.123.83, 2.41.4, and 2.42.1 contains a server-side request forgery vulnerability in the Slack Trigger webhook that allows unauthenticated attackers to exfiltrate Slack tokens by bypassing signature verification when no signing secret is set. Attackers who know the webhook URL can name a file to download, causing the node to send the workspace access token to an attacker host and return the response.

CWE
- CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains a prototype pollution vulnerability that allows low-privileged users to alter built-in object behaviour by saving workflows with specially named connection keys. Attackers can add keys such as __proto__ to workflow connections, which the periodic history compaction task processes, causing logins and writes to fail with server errors.

CWE
- CWE-939 - Improper Authorization in Handler for Custom URL Scheme
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains a missing confirmation vulnerability in the Local Gateway desktop app that allows its deep-link connect handler to silently re-pair the app with a different n8n instance. Attackers can lure users running the Local Gateway into opening a crafted n8n-computer-use:// link to connect their computer to an attacker-controlled instance, inheriting previously granted permissions and acting on the computer through the gateway.

- CWE-863 - Incorrect Authorization
Summary
n8n before 1.123.85, 2.43.5, and 2.44.1 contains a credential guard bypass vulnerability that allows editors of shared workflows to use restricted credentials by loading sub-workflows from URLs or local files. Attackers can configure the Execute Sub-workflow node with source url or localFile to serve content that resolves project credentials and returns their decrypted values.

Summary
n8n before 2.43.5 and 2.44.x before 2.44.1 accepts a client-supplied workflow ID and caches each workflow's owner project in memory by that ID, so a crafted ID such as __proto__ makes the Data Table project check match every project. An authenticated member who can create and run workflows can list, read, modify, and delete Data Table rows in all projects of the instance.

- CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Summary
n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 contains a stored cross-site scripting vulnerability because some webhook response paths, such as error responses and responses without headers, omit the sandbox Content-Security-Policy. Authenticated members who can create and activate workflows can serve HTML that runs on the n8n origin, letting scripts act with the session of users who open the webhook URL.

Summary
n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 saves the SeaTable Trigger node's API token in error execution data, because failed poll requests store raw request headers. Users who can view workflow executions but cannot read the credential can recover the token and access the connected SeaTable base.

CWE
- CWE-1333 - Inefficient Regular Expression Complexity
Summary
n8n before 1.123.85, 2.43.5, and 2.44.1 contains a regular expression denial of service vulnerability that allows authenticated members to block the event loop via crafted glob patterns. Attackers who can create and run workflows can submit a wildcard-heavy File(s) Selector pattern causing exponential backtracking, making the UI, API, webhooks, and health checks unresponsive until restart.

Summary
n8n before 2.41.5 and 2.42.x before 2.42.2 passes a failed workflow's full execution context, including the identity of the user who started the run, to the configured error workflow. A project editor can set a colleague's workflow settings.errorWorkflow to an error workflow they own, inherit the colleague's identity when that workflow fails, and resolve the colleague's per-user dynamic credential secrets.

- CWE-209 - Generation of Error Message Containing Sensitive Information
Summary
n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 stores credential secrets in execution error data when operations fail in the Git, MongoDB Atlas Vector Store, and Google Cloud Storage nodes. Users who can view a workflow's executions but cannot read the credential can recover Git passwords or tokens, MongoDB database passwords, or Google access tokens from that data.

CWE
- CWE-863 - Incorrect Authorization
Summary
n8n before 1.123.85, 2.43.5, and 2.44.1 contains an authorization bypass vulnerability that allows authenticated members to use inaccessible credentials through inline sub-workflow nodes with non-boolean disabled values. Attackers knowing a credential id can run Execute Workflow nodes in inline JSON mode that skip the permission check and send decrypted credentials to attacker-controlled servers.

Summary
n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 contains an OData $filter injection vulnerability in the Microsoft Outlook contact lookup and Microsoft SharePoint v1 item update nodes, which build $filter string literals from expression-bindable parameters without escaping. Attackers who supply untrusted input to such workflows can inject single quotes to dump the bound mailbox's entire contact list or redirect SharePoint writes onto unintended list items within the stored credential's scope.

- CWE-288 - Authentication Bypass Using an Alternate Path or Channel
Summary
n8n before 1.123.83, 2.x before 2.41.4, and 2.42.x before 2.42.1 contains an authentication bypass because dynamic-path webhook resolution matched requests on the path alone, ignoring the server-generated identifier that is the URL's only unguessable component. Unauthenticated attackers can omit this identifier in requests to webhook, form, or MCP routes to execute workflows in unrelated projects under those projects' credentials.

CWE
- CWE-639 - Authorization Bypass Through User-Controlled Key
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains an authorization bypass in the Agents create endpoint, which accepts a caller-supplied Agent ID, checks permissions only against the requested project, and updates an existing Agent without verifying which project owns it. An authenticated user with read-only Agent access to another project can supply an existing Agent ID to move that Agent into their own project and rewrite its name, schema and version.

CWE
- CWE-863 - Incorrect Authorization
Summary
n8n before 2.41.4 and 2.42.0 before 2.42.1 does not validate credential ids stored in agent node parameters when an editor saves a shared workflow, because the check inspects only a node's credentials field. An editor can configure a Message an Agent node in inline mode with tools they control to resolve the owner's credentials and send decrypted secrets to an attacker-chosen destination.

- CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
Summary
n8n before 1.123.83, 2.x before 2.41.4, and 2.42.x before 2.42.1 contains a prototype pollution vulnerability in the AI workflow builder, which merges workflow connections using node names as object members without checking for reserved keys. Authenticated users can create nodes named __proto__ through the API and invoke the connect-nodes operation to pollute the global object prototype, disrupting the instance until restart.

- CWE-180 - Incorrect Behavior Order: Validate Before Canonicalize
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains a signature bypass in the waiting-webhook endpoint, which selects Send-and-Wait validation before normalising an alternate node reference form. Attackers holding an execution's resume token can approve waiting executions meant for others, running downstream actions under the workflow owner's credentials, potentially including command execution.

CWE
- CWE-770 - Allocation of Resources Without Limits or Throttling
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains an uncontrolled resource consumption vulnerability in the unauthenticated OAuth authorize endpoint, which resolves clients by URL path but stores the caller's raw identifier as the record key. Unauthenticated attackers can send identifiers differing only in their query string to create unlimited first-party client records that bypass the registration cap, growing the database until the disk fills.

CWE
- CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains a prototype pollution vulnerability in the MCP workflow-validation tool, whose interpreter evaluates caller-supplied code in the main process, reads inherited properties, and permits assignment onto shared prototypes. An authenticated member holding only a workflow:read grant can replace a built-in method with one returning a truthy value so server-side permission checks accept unheld scopes, enabling takeover of owner accounts not protected by MFA.

CWE
- CWE-639 - Authorization Bypass Through User-Controlled Key
Summary
n8n before 2.41.4 and 2.42.0 contains an authorization bypass in the agent chat resume endpoint, which accepts a run identifier from the request body without verifying that the suspended checkpoint belongs to the caller. Authenticated project members can list and read other members' private agent conversations through project-scoped endpoints, then approve their pending tool calls, causing the tools to execute and write results into the victim's conversation.

CWE
- CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
n8n before 2.41.4 and 2.42.x before 2.42.1 contains an SQL injection vulnerability in version 1 of the Microsoft SQL node, which substitutes Query field expression values directly into SQL text without parameterisation. When a workflow binds untrusted input such as webhook fields to the Query field, unauthenticated external callers can execute arbitrary SQL against the connected database with the stored credential's privileges.
