Script execution in another user's browser

Published Sep 2, 2026 · Updated Sep 2, 2026

Cross-site scripting in Drupal Screenshot all versions allows remote authenticated users to execute script in another user's browser. Drupal has not published the affected code locus, the untrusted input, or the operation that fails to neutralize it before web-page output. Exploitation requires high privileges and another user's interaction; successful script can read or alter data in that user's Drupal session but does not interrupt service.
