Title
n8n before 1.123.83, 2.41.4, and 2.42.1 Slack Token Exfiltration via Slack Trigger
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.

Title
n8n before 2.41.4 and 2.42.1 Prototype Pollution DoS via Workflow History Compaction
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.

Title
n8n before 2.41.4 and 2.42.1 Local Gateway Deep-Link Silent Re-pairing to Attacker Instance
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.

Title
n8n before 2.43.5 and 2.44.1 Authorization Bypass via Crafted Workflow ID in Data Tables
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.

Title
n8n before 1.123.85, 2.43.5, and 2.44.1 Stored XSS via Webhook Responses Missing Sandbox Policy
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.

Title
n8n before 1.123.85, 2.43.5, and 2.44.1 SeaTable Trigger API Token Exposure via Execution Data
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.

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.

Title
n8n before 2.41.5 and 2.42.2 Credential Theft via Error-Workflow Context Inheritance
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.

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.

Title
n8n before 1.123.85, 2.43.5, and 2.44.1 OData $filter Injection via Outlook and SharePoint Nodes
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.

Title
n8n before 1.123.83, 2.41.4, and 2.42.1 Slack Token Exfiltration via Slack Trigger
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.

Title
n8n before 2.41.4 and 2.42.1 Prototype Pollution DoS via Workflow History Compaction
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.

Title
n8n before 2.41.4 and 2.42.1 Local Gateway Deep-Link Silent Re-pairing to Attacker Instance
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.

Title
n8n before 2.43.5 and 2.44.1 Authorization Bypass via Crafted Workflow ID in Data Tables
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.

Title
n8n before 1.123.85, 2.43.5, and 2.44.1 Stored XSS via Webhook Responses Missing Sandbox Policy
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.

Title
n8n before 1.123.85, 2.43.5, and 2.44.1 SeaTable Trigger API Token Exposure via Execution Data
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.

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.

Title
n8n before 2.41.5 and 2.42.2 Credential Theft via Error-Workflow Context Inheritance
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.
