Summary
n8n: Stored DOM XSS via Resource Locator `cachedResultUrl`
Details

Impact

The Resource Locator passes the workflow-persisted cachedResultUrl to window.open() without scheme validation. When a victim opens the crafted workflow and interact with external links, the JavaScript payload runs in the victim's browser.

Patches

The issue has been fixed in n8n versions 1.123.64, 2.29.8, and 2.30.1. 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: - Restrict workflow creation and editing permissions to fully trusted users only. - Audit existing workflows for unexpected cachedResultUrl values containing non-HTTP(S) schemes.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
