CVE-2025-7715Network attack vector

Stored XSS via unchecked event attributes

Published Jul 21, 2025 · Updated Jul 22, 2025

Stored XSS in Drupal Block Attributes before 1.1.0 and 2.0.0 allows remote authenticated users to run JavaScript in visitors' browsers. The module accepts custom attribute names without blocking JavaScript event handlers such as onmouseover or onkeyup, then renders them into block markup. Exploitation requires manually adding the event attribute and its script through the block configuration form; execution occurs when a visitor triggers the rendered event, exposing or modifying browser-accessible data.
