CyberRota Analysis
AI-GeneratedThe OAuth token endpoint in n8n versions prior to 2.37.7 and 2.38.1 is vulnerable, allowing an attacker to exploit the refresh token mechanism by substituting a different workflow URL. This could enable unauthorized access to workflows, potentially compromising sensitive data or actions within the platform. Organizations using n8n for workflow automation should prioritize upgrading to the patched versions to mitigate this security risk.

Original NVD Description
n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.1, the OAuth token endpoint bound an authorization code's first access token to the consented resource but did not bind its refresh token. Refreshing checked only that the requested resource was registered, not that it matched the original grant. An OAuth client approved for one workflow could substitute a different workflow URL in the resource parameter and obtain a valid token for an unapproved workflow accessible to the consenting user. This issue is fixed in versions 2.37.7 and 2.38.1.
