CVE-2026-12622Network attack vector

Authenticated redirection via unvalidated redirectUrl parameter

Published Jun 19, 2026 · Updated Jun 19, 2026

Open redirect in the password change form in Microchip GridTime 3000 1.0r0.03 through 1.1r0.0 allows remote authenticated users to redirect browsers. The form accepts a crafted redirectUrl parameter and sends the browser to an uncontrolled URL without validating the destination. Valid device credentials are required, and the documented consequence is redirection to an attacker-selected site.
