CVE-2026-65592
Full vulnerability record from the local CVENow database.
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.

"value": "n8n antes de 1.123.64, 2.29.8 y 2.30.1 contiene una vulnerabilidad de cross-site scripting DOM almacenado en el componente Resource Locator, que pasa el parámetro cachedResultUrl persistido en el flujo de trabajo a window.open() sin validación de esquema. Un atacante con privilegios de creación/edición de flujos de trabajo puede crear un flujo de trabajo con un esquema malicioso (p. ej., javascript_disabled: ) en cachedResultUrl; cuando una víctima abre el flujo de trabajo creado e interactúa con enlaces externos, la carga útil se ejecuta en el navegador de la víctima."
