n8n: Stored DOM XSS via Resource Locator `cachedResultUrl`
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
## 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.
