    Missing Authorization

    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.

    How to fix Missing Authorization?

    Uncaught Exception

    n8n is a n8n Workflow Automation Tool

    Affected versions of this package are vulnerable to Uncaught Exception via the /rest/binary-data endpoint when handling empty filesystem URIs. An authenticated attacker can cause resource exhaustion and disrupt service availability by sending specially crafted GET requests with empty filesystem:// or filesystem-v2:// URIs to the affected endpoint.

    How to fix Uncaught Exception?

    Upgrade n8n to version 1.99.0 or higher.

    <1.99.0

    Cross-site Scripting (XSS)

    n8n is a n8n Workflow Automation Tool

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via a lack of MIME type validation on uploaded binary files, which can be controlled through a GET parameter. This allows an authenticated attacker with member-level privileges to upload a crafted HTML file containing malicious code. If another authenticated user visits the binary data endpoint with the MIME type specified as text/html, the embedded script will execute within the user's browser session, potentially enabling account takeover, for instance, by initiating an unauthorized email address change.

    How to fix Cross-site Scripting (XSS)?

    Upgrade n8n to version 1.90.0 or higher.

    <1.90.0
