CVE-2026-65592 Details
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.
A stored DOM cross-site scripting vulnerability has been identified in n8n versions prior to 1.123.64, 2.29.8, and 2.30.1. The issue arises in the Resource Locator component, where the workflow-persisted 'cachedResultUrl' parameter is passed to 'window.open()' without proper scheme validation. This vulnerability allows an attacker with workflow creation or editing privileges to craft a workflow containing a malicious URL scheme, such as 'javascript:'. When a victim opens the manipulated workflow and interacts with external links, the embedded JavaScript payload executes in the victim's browser.
Users are advised to upgrade to n8n versions 1.123.64, 2.29.8, or 2.30.1. If an immediate upgrade is not possible, workflow creation and editing permissions should be restricted to trusted users, and existing workflows should be audited for 'cachedResultUrl' values containing non-HTTP(S) schemes.
