GHSA-364x-8g5j-x2pr:
n8n vulnerability analysis and mitigation
Impact
An authenticated user with permission to create and share credentials could craft a malicious OAuth2 credential containing a JavaScript URL in the Authorization URL field. If a victim opened the credential and interacted with the OAuth authorization button, the injected script would execute in their browser session.
Patches
The issue has been fixed in n8n versions 2.8.0 and 2.6.4. Users should upgrade to one of these versions or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Limit credential creation and sharing permissions to fully trusted users only.
- Restrict access to the n8n instance to trusted users only. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
