Stored XSS via unfiltered administrator text
Published Feb 4, 2026 · Updated Feb 4, 2026
Stored XSS in Drupal AT Internet SmartTag before 1.0.1 allows remote authenticated users to run script through administrator-entered text. The module stores administrator-supplied SmartTag configuration text without filtering it before generating a web page, causing browsers to interpret injected markup or script. Exploitation requires the administer atsmarttag permission; successful payloads execute in a later viewer's browser with that viewer's session privileges.
