Stored XSS via unfiltered administrator text
Published Feb 4, 2026 · Updated Feb 4, 2026
Stored XSS in Drupal AT Internet Piano Analytics before 1.0.1 and 2.0.0 through 2.3.0 allows remote authenticated users to run script. The module stores administrator-entered configuration text without filtering it before including it in generated pages. A role with the administer pianoanalytics permission must save the payload; later page rendering executes it in visitors’ browsers, allowing data access or actions within those sessions.
