Summary
n8n before 1.123.64, 2.29.8, and 2.30.1 contains a stored DOM cross-site scripting vulnerability in the Resource Locator component, which passes the workflow-persisted cachedResultUrl parameter to window.open() without scheme validation. An attacker with workflow creation/editing privileges can craft a workflow with a malicious (e.g., javascript:) scheme in cachedResultUrl; when a victim opens the crafted workflow and interacts with external links, the payload executes in the victim's browser.
