CVE-2025-10931Network attack vector

Admin-level JavaScript execution via unflagged permission

Published Oct 29, 2025 · Updated Oct 29, 2025

Cross-site scripting in Drupal Umami Analytics before 1.0.1 allows remote authenticated users to execute JavaScript on site pages. The administer umami analytics permission accepts an arbitrary JavaScript file for inclusion on every page but lacks Drupal's restrict access flag. A role with that administrative permission is required; injected code executes in browsers that render affected site pages.
